Generally, if cracks occur in concrete due to deterioration etc., it may cause fatal defects due to deterioration of waterproof performance, corrosion of reinforcing steel, deterioration of durability, and decrease of strength.
Cracks in concrete are often caused by various factors such as external environmental factors such as deterioration, deterioration, material properties such as design load, plastic shrinkage or drying shrinkage, mixing conditions, and construction factors.
If cracks occur in the concrete structure due to various factors such as this, the concrete structure can not withstand the load and may collapse. Therefore, in order to recover the waterproofness and durability of the cracked concrete structure, It is necessary to repair it.
In addition, chemical corrosion is a general term of deterioration phenomenon in which concrete receives external chemical action and loses bonding ability by modifying or decomposing the hydration product constituting the hardened cement body.
It is easy to be confused with the deterioration phenomenon by existing neutralization, East Sea and salting, and the concrete structure is not replaced with the sulfuric acid repair mortar, but the existing repair mortar is poured into the concrete structure, resulting in deterioration such as cracking or peeling in the structure, There has been a problem that it is rapidly deteriorated.

Hereinafter, preferred embodiments according to the present invention will be described in detail. However, it should be understood that the following embodiments are provided so that those skilled in the art will be able to fully understand the present invention, and that various modifications may be made without departing from the scope of the present invention. It is not.
A high-performance cement concrete composition (hereinafter referred to as a 'high-performance cement concrete composition') using a solar cell silicon wastewater sludge solid-liquid separation dry matter according to a preferred embodiment of the present invention includes cement binder, fine aggregate, coarse aggregate and water.
The cementitious material is contained in an amount of 3 to 38 parts by weight based on the high-performance cement concrete composition, the fine aggregate is contained in 20 to 70 parts by weight with respect to the high-performance cement concrete composition, and the coarse aggregate is added to the high- To 60 parts by weight, and the water is contained in an amount of 0.1 to 10 parts by weight with respect to the high-performance cement concrete composition.
Aggregates are classified into fine aggregate and coarse aggregate, and those with a grain size of 5 mm or less are referred to as fine aggregate and those having a grain size larger than 5 mm are classified into coarse aggregate.
The fine aggregate is preferably contained in the high-performance cement concrete composition in an amount of 20 to 70 parts by weight, and the coarse aggregate is preferably contained in the high-performance cement concrete composition in an amount of 10 to 60 parts by weight.
Wherein the cement binder comprises 26 to 80 parts by weight of Portland
The cement binder may further contain 1 to 3 parts by weight of a high performance binder.
Further, the cement binder may further contain 0.1 to 2 parts by weight of an extrudate.
The cement binder is preferably contained in an amount of 3 to 38 parts by weight based on the high-performance cement concrete composition. .
If the content of the cement binder exceeds 38 parts by weight based on the high-performance cement concrete composition, workability, strength and durability are improved but drying shrinkage and economic efficiency may be deteriorated. If the content of the cement- If the amount is less than 3 parts by weight, the drying shrinkage is small, but the strength and durability may be lowered.
Next, the construction of the cement-based material will be described in detail.
The above-mentioned cement may be cement or slag cement of one kind to five kinds of ordinary portland specified in KS.
The solid-liquid separation and drying of the silicon wafer waste sludge shows the pozzolanic reaction characteristic (Reaction 1) in which soluble Ca (OH) 2 is converted into insoluble CSH containing SiO 2 as shown in Table 1, (reaction formula 2) in which hydrogen (free-Si) is contained to generate hydrogen gas. Therefore, not only crack reduction effect and durability improvement effect but also reaction of silicon metal is exothermic reaction It accelerates the hydration reaction of cement, induces high initial strength, and has the function of solving side effects due to delayed condensation when using gypsum.
Scheme 1: mSiO2 + nCa (OH) 2 → nCaOmSiO2nH 2 O
Reaction 2: free-Si + 2H 2 O → SiO 2 + 2H 2 ↑
It is preferable that 1 to 50 parts by weight of the silicon wafer waste sludge solid-liquid separation dry matter is contained in the cement binder.
If the content of the solid-liquid separation and drying product of the silicon wafer waste sludge is less than 1 part by weight, the initial reactivity of the composition may be lowered and the initial strength development, drying shrinkage preventing effect and durability improving effect may be deteriorated. If the content of the solid-liquid separation and drying product of the silicon wafer waste sludge is more than 50 parts by weight, the initial strength and durability of the composition are improved but the heat of hydration is increased, which may cause over expansion and cracking.
The gypsum (CaSO 4 ) reacts with the components in the cement, in particular, C 3 A ( 3 CaOAl 2 O 3 ) to form an acicular structure (AFt phase, C 3 A 3 CaSO 4 32 H 2 O) Thereby exhibiting durability enhancement and strength enhancement effects.
However, excessive gypsum has a disadvantage in that the amount of the gypsum is limited under portland cement conditions because it slows the condensation of the cement and restrains the initial reaction. However, due to the high initial reactivity of the silicon wafer waste sludge, It is possible to use a large amount of gypsum compared to existing cement, which not only improves initial strength and long-term strength, but also enables durability of concrete by densification of the structure.
The gypsum is preferably contained in the cement binder in an amount of 1 to 15 parts by weight.
If the content of gypsum is less than 1 part by weight, the initial formation of etinzate is reduced and the formation of dense structure is difficult. When the amount of gypsum is more than 15 parts by weight, May cause expansion cracks and condensation delays.
The water reducing agent is used to improve the strength and durability by reducing the water-cement ratio of the cement mortar composition.
The water reducing agent may be a polycarboxylic acid type, melamine type, aminosulfonic acid type or naphthalene type fluidizing agent.
Here, the melamine-based or naphthalene-based water reducing agent is less effective in improving the strength and durability than the polycarboxylic acid-based water reducing agent, has a small effect of reducing the water-cement ratio, and has poor compatibility when mixed with the polymer binder There is a disadvantage.
Therefore, it is preferable that the water reducing agent is a polycarboxylic acid based water reducing agent and 0.01 to 5 parts by weight of the water reducing agent is contained in the cement binder.
The defoaming agent is used for converting the large bubbles generated by the initial hydrogen-forming reaction of the solid-liquid separation and drying of the silicon wafer waste sludge of the high-performance cement concrete composition into a micropore and for containing appropriate air to improve the resistance to freezing and thawing do.
The antifoaming agent may be selected from the group consisting of an alcohol type antifoaming agent, a silicone type antifoaming agent, a fatty acid type antifoaming agent, an oil type antifoaming agent, an ester type antifoaming agent and an oxyalkylene type antifoaming agent. ≪ / RTI > may be used.
Examples of the silicone defoaming agent include dimethyl silicone oil, polyorganosiloxane, and fluorosilicone oil.
As the fatty acid defoaming agent, stearic acid, oleic acid, and the like can be used. As the oil defoaming agent, kerosene, animal oil, castor oil and the like can be used. Examples of the ester type defoaming agent include solitol trioleate, glycerol monolithic acid Nolate, etc. may be used. As the oxyalkylene antifoaming agents, polyoxyalkylene, acetylene ethers, polyoxyalkylene diazoxide esters, polyoxyalkylene alkylamines and the like can be used. As the alcohol type antifoaming agents, glycol (glycol) may be used.
The antifoaming agent is preferably contained in an amount of 0.01 to 5 parts by weight based on the performance improving agent.
Next, the cement binder may further optionally contain 1 to 3 parts by weight of a high-performance binder and 0.1 to 2 parts by weight of an inorganic fine powder, depending on purposes and purposes.
First, the high performance binder is composed of 22.99 to 25.67 parts by weight of a polycarboxylic acid solution, 22.99 to 25.67 parts by weight of a cellulose powder, and 22.99 to 25.67 parts by weight of aluminum hydroxide (Al (OH) 3 ) Thereby enhancing the bonding force between the particles.
The extrudate is added to increase the friction of the road, and is preferably a sand paper having a grain size of 0.3 mm or less.
The reason for limiting the amount of the above-mentioned extrudate to 0.1 to 2 parts by weight is that the effect of increasing the friction is insufficient when the amount is less than 0.1 part by weight, and the binding force of the whole mixture is decreased when the amount is more than 2 parts by weight.
The high-performance cement concrete composition according to the preferred embodiment of the present invention can be produced by the following method.
Cement binder, fine aggregate and coarse aggregate are mixed at a certain ratio and stirred in a forced mixer. The cement binder is mixed with 3 to 38 parts by weight of the high-performance cement concrete composition, and the fine aggregate is mixed with 20 to 70 parts by weight of the high-performance cement concrete composition.
