Description
Technical field
The present invention relates to novel wall material technical field, is a kind of load bearing heat preserving anti-cracking cotton stalk cement based building block and preparation method thereof.
Background technology
The destruction of Concrete Material is mainly because the development that load and environmental influence produce hidden microfracture and microfracture causes.Concrete eakiness makes the infiltration of water and other soluble material accelerate the process of destroying.Improve concrete quality, stop the development and change in crack particularly to merit attention.From the force-mechanism of Study on Steel fiber reinforced concrete in 1963, it is found that fiber has strengthened the substantial connection between gelling material greatly, thereby tensile strength and the crack resistance of Concrete Material are improved, the research mushroom development of fiber reinforced concrete is got up, steel fiber, glass fibre, the concrete technology of the enhancings such as polypropylene fibre has been applied to obtain comparative maturity, but the corrosion of reinforcing bar is the major cause that affects concrete structure durability, easily there is corrosion problem at crack place in steel fiber, particularly in contaminated place, become a thorny old problem, and the price of these fibers is also relatively costly, increase concrete cost.In recent years in developing countries and regions, utilize the vegetable fibre of relative low price to strengthen concrete interest and grow with each passing day.The advantages such as vegetable fibre is the natural macromolecular material that nature enriches the most, and it is large that the fibre shape of vegetable fibre has length-to-diameter ratio, and specific tenacity is high, and specific surface area is large.Research and development Plant Fiber Cement-based Composite Materials With Steel Slag not only can reduce concrete cost, and is conducive to environmental protection and Sustainable development, has profound significance.
Xinjiang produces main base as Cotton in China, produces every year a large amount of cotton stalks.2010,2,500 ten thousand mu of cotton in Xinjiang cultivated areas, cotton stalk output is more than 1,000 ten thousand tons.Rationally and effectively these cotton stalks are developed into renewable energy source, to Development in Xinjiang rural economy, promote local economic development, accelerate Xinjiang building Socialist New and will play positive pushing effect.At present, Xinjiang is processed the method for cotton stalk and is mainly contained 2 kinds: the one, and direct burning, the low and contaminate environment of thermo-efficiency.The 2nd, make bar machine with cotton and smash rear emergency burial, because cotton stalk is closely knit and cotton growing area is dry, be difficult to corrosion, cotton stalk more slightly can not become fertilizer in time, repeatedly buries the burden that has increased soil, and the fertility of soil is declined.How effectively to develop the cotton stalk resource in Xinjiang, promote Rural Area of Xinjiang Autonomous Region Economic development, become current major issue urgently to be resolved hurrily.
The materials for wall major function of existing block masonry structure has been load-bearing effect, and walling thermal property is poor, and thermal conductivity is high, if reach country's energy-conservation requirement of present stage, body of wall also needs to do outer insulation, has so not only increased overall cost, but also has extended construction period.
The heat insulating building blocks such as existing air-entrained concrete building block, cinder concrete piece, haydite concrete piece, thermal property is good, but intensity is all lower, can only do retaining wall materials'use, and this class building block quality is more crisp, easily broken destruction, and resistance to cleavage is poor.
Summary of the invention
The invention provides a kind of load bearing heat preserving anti-cracking cotton stalk cement based building block and preparation method thereof, overcome the deficiency of above-mentioned prior art, it is high and cause the building block of steel fiber feinforced cement base to affect the problem of concrete structure durability because reinforcing bar is perishable that it can effectively solve the cement based building block costs such as existing steel fiber, glass fibre, polypropylene fibre; Thereby can effectively solve, bearing wall material thermal property is poor also to be needed to do secondary insulation and affects the problem of overall cost; Can effectively solve that existing heat insulating building block resistance to cleavage is poor, intensity is low can only do the problem that building enclosure materials for wall uses.
One of technical scheme of the present invention realizes by following measures: the building block of a kind of load bearing heat preserving anti-cracking cotton stalk cement based, obtain in the steps below: the first step: first cotton stalk is broken into the cotton stalk particle that length is 10mm to 50mm, be 1% to 2% NaOH solution soaking 24 hours to 36 hours by cotton stalk particle by mass concentration, then the cotton stalk particle clear water soaking is rinsed and washes away alkali lye, after having rinsed, cotton stalk particle draining is dried as cotton stalk siccative for subsequent use; Second step: meter by weight, takes respectively 240 parts to 320 parts, 80 parts to 120 parts of cotton stalk siccatives, 400 parts to 500 parts of cement, 1000 parts to 1500 parts, sand, 2 parts to 3.5 parts of aluminium powders, 4 parts to 6 parts of water reducers and water; The 3rd step: load weighted aluminium powder, cement are mixed with sand, and dry mixing evenly becomes cement sand mixture, more load weighted cotton stalk siccative is poured in cement sand mixture and stirred, just finished product mixture after stirring, obtained; The 4th step: load weighted water reducer is poured in load weighted water and is stirred into the water reducer aqueous solution, the water reducer aqueous solution is poured in first finished product mixture and is uniformly mixed and obtains mixture; The 5th step: mixture is entered to mould and vibrates, vibrate after having operated and obtain pattern, at pattern surface coating, leave standstill after 24 hours form removal the building block of load bearing heat preserving anti-cracking cotton stalk cement based.
Two of technical scheme of the present invention realizes by following measures: the preparation method of a kind of load bearing heat preserving anti-cracking cotton stalk cement based building block carries out in the steps below: the first step: first cotton stalk is broken into the cotton stalk particle that length is 10mm to 50mm, be 1% to 2% NaOH solution soaking 24 hours to 36 hours by cotton stalk particle by mass concentration, then the cotton stalk particle clear water soaking is rinsed and washes away alkali lye, after having rinsed, cotton stalk particle draining is dried as cotton stalk siccative for subsequent use; Second step: meter by weight, takes respectively 240 parts to 320 parts, 80 parts to 120 parts of cotton stalk siccatives, 400 parts to 500 parts of cement, 1000 parts to 1500 parts, sand, 2 parts to 3.5 parts of aluminium powders, 4 parts to 6 parts of water reducers and water; The 3rd step: load weighted aluminium powder, cement are mixed with sand, and dry mixing evenly becomes cement sand mixture, more load weighted cotton stalk siccative is poured in cement sand mixture and stirred, just finished product mixture after stirring, obtained; The 4th step: load weighted water reducer is poured in load weighted water and is stirred into the water reducer aqueous solution, the water reducer aqueous solution is poured in first finished product mixture and is uniformly mixed and obtains mixture; The 5th step: mixture is entered to mould and vibrates, vibrate after having operated and obtain pattern, at pattern surface coating, leave standstill after 24 hours form removal the building block of load bearing heat preserving anti-cracking cotton stalk cement based.
