The preparation method of the mortar is simple to operate, is easy to make, and effectively improves the producing efficiency of mortar.
Embodiment
, below will be in the embodiment of the present invention to make the purpose, technical scheme and advantage of the embodiment of the present invention clearer
Technical scheme be clearly and completely described.Unreceipted actual conditions person, builds according to normal condition or manufacturer in embodiment
The condition of view is carried out.Agents useful for same or the unreceipted production firm person of instrument, it is the conventional production that can be obtained by commercially available purchase
Product.
Mortar of the embodiment of the present invention and preparation method thereof is specifically described below.
The present invention provides a kind of mortar, and it includes：The cement of 10-13 parts by weight, the sand of 50-70 parts by weight, 1-3 parts by weight
Marble powder, the water of 8-15 parts by weight, and the additive of 0-0.3 parts by weight.By the rational proportion of above-mentioned material, obtain
Quality preferably mortar, it has preferable workability.For example, mortar can include：The cement of 10-13 parts by weight, 50-70 weights
Measure the sand of part, the marble powder of 1-3 parts by weight, and the water of 8-15 parts by weight；Mortar can also include the water of 10-13 parts by weight
Mud, the sand of 50-70 parts by weight, the marble powder of 1-3 parts by weight, and the water of 8-15 parts by weight, and 0-0.3 parts by weight are outer
Add agent.
The chemical composition of marble powder is carbonic acid grey matter crystalline solid, is carrier using marble, additive is easier to point
Dissipate uniform.
Wherein, the raw material of marble powder is artificial marble dead meal and/or natural marble dead meal.Repeat to reclaim profit
With, the utilization rate of artificial marble dead meal or natural marble dead meal is improved, it is green.
Preferably, the particle diameter of marble powder is 50nm-10um.Marble powder in the particle size range can be effectively improved mortar
The grading of fine particle, that is, improve size distribution of the powder body material in mortar, produce dense packing filing effect, make mortar
Pore structure optimizes, while improves the workability of mortar mixture.
Preferably, husky granularity is 0.5-2.5mm, is easy to mix, and improves the sophistication of mortar.
But fragility to be present big for traditional mortar, cohesive force deficiency, the problems such as wall is low are adapted to.Preferably, additive bag
It is 1-2 to include weight ratio：0.05-0.2 rubber powder and polypropylene fibre.For improving the modulus of elasticity of mortar, cracking resistance, toughness etc.
Property.
Wherein, rubber powder can change mortar from microscopic dimensions, improve as a kind of high polymer elastic solid particulate materials
The elasticity of mortar, meanwhile, the use of rubber powder makes waste rubber turn waste into wealth, and realizes the recycling of waste rubber goodses, simultaneously
Also solve the problem of environmental pollution of waste rubber goodses, because junked tire class rubber has stronger heat resistance, resist
Corrosivity, aging and natural decomposition ability, burning processing can bring more serious air pollution again, upper a century after buried processing
All it is not easy to be completely broken down, thus the harmless treatment of waste old material and the application in mortar engineering are also development green
One important development direction of mortar, the present invention can not only solve pollution of the rubber type of material to environment, also improve simultaneously
The toughness of mortar material, the defects such as the deformation that solves mortar is small, fragility is big, tensile capacity is low.
But undressed rubber powder is directly added into mortar, although improving the toughness of mortar, mortar is caused
Intensity loss.
It is preferred that after rubber powder is strong base solution pretreatment, pass through the rubber powder after silane coupler modified.By
Strong base solution surface modifications, make the viscosity increase on the surface of rubber powder, then further by silane coupler modified, effectively increase
Interface cohesive force greatly between rubber powder and mortar.
Specifically, in preferred embodiments of the present invention, rubber powder is made by following methods：
Rubber powder raw material is put into strong base solution after 10min-30min, is immersed in after drying in silane coupler, is dried
It is dry.
Wherein, highly basic can be sodium hydroxide, potassium hydroxide etc., and in the present invention, preferably sodium hydroxide, its price is more
It is cheap, and preservation condition is more convenient compared to potassium hydroxide.And the spot on rubber powder surface etc. is effectively removed, makes its surface
It is easier to react with silane coupler.Preferably, strong base solution is 1-3mol/L sodium hydroxide, and treatment effect is good.
Preferably, the particle size of rubber powder provided by the invention is 40-80 mesh, should in the range of, its cementation more preferably,
It is more convenient for surface modifications.
Preferably, silane coupler is preferably silane coupler KH-151, has the effect of coupling agent and crosslinking agent concurrently, makes rubber
The effect of interface cohesive force between rubber powder and mortar is stronger.
By modified rubber powder, effectively increase the toughness of mortar, while after effective compensation adds rubber powder
The loss amount of the intensity of mortar.
Polypropylene fibre has stronger alkali resistance, is not corroded by various alkaline base-material hydrated products；Good point of tool
Property is dissipated, does not unite, not bunchy, ensure that its being uniformly distributed in base material of mortar；With higher toughness and intensity, mixing
Balling-up of bending is not easy in stirring.
Therefore, the addition of polypropylene fibre, the anti-crack ability of mortar is effectively improved, meanwhile, in order to reduce addition polypropylene
The loss of the intensity of mortar caused by fiber, it is preferable that polypropylene fibre is fine by the polypropylene after silane coupler modified
Dimension.Effect by the interface cohesive force between the polypropylene fibre and mortar after silane coupler modified is stronger.Specifically, gather
After tacryl is soaked in silane coupler 5-10min, take out, drying.
Preferably, the length of PP type fiber is 15-25mm.Wherein, polypropylene fibre can effectively improve the (anti-of mortar
Tensile, compressive, bending) intensity, toughness, ductility, impulse fatigue resistance energy and deformation modulus, and meanwhile it is cheap, it is easy for construction.It is preferred that
Ground, the length of PP type fiber is 15-25mm.Be easy to be scattered in mortar, further enhance the incompressible deformability of mortar,
The performances such as flexural capacity.
The present invention also provides a kind of preparation method of above-mentioned mortar, including：It is husky by cement, marble powder, water, and outside
Add agent to mix, carried out wherein being mixed in mixer, specifically, at least 10min is mixed under 600-1000r/min rotating speed,
Its composition is mixed, improves the workability and intensity of mortar.
The feature and performance of the present invention are described in further detail with reference to embodiments.
