Description
Technical field
The present invention relates to the 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 mainly is to cause owing to development that load and environmental influence produce hidden microfracture and microfracture.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 the gelling material greatly, thereby tensile strength and the crack resistance of Concrete Material have been 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 used to get comparative maturity, yet the corrosion of reinforcing bar is the major cause that affects concrete structure durability, the corrosion problem occurs at the place, crack in steel fiber easily, particularly in contaminated place, become a thorny old problem, and the price of these fibers is also relatively costly, has increased 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 abundantest natural macromolecular material of nature, 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.The 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, a large amount of cotton stalks of annual generation.2010,2,500 ten thousand mu of cotton in Xinjiang cultivated areas, cotton stalk output were more than 1,000 ten thousand tons.Rationally and effectively these cotton stalks are developed into renewable energy source, to the Development in Xinjiang rural economy, promote local economic development, accelerate the Xinjiang building Socialist New and will play positive pushing effect.At present, the method that cotton stalk is processed in Xinjiang mainly contains 2 kinds: the one, and direct burning, the low and contaminate environment of thermo-efficiency.The 2nd, make the bar machine with cotton and smash rear emergency burial, because cotton stalk is closely knit and the cotton growing area is dry, be difficult to corrosion, cotton stalk more slightly can not in time become fertilizer, repeatedly buries the burden that has increased soil, and the fertility of soil is descended.How effectively to develop the cotton stalk resource in Xinjiang, promote the Rural Area of Xinjiang Autonomous Region Economic development, become the current major issue that needs to be resolved hurrily.
The materials for wall major function of existing block masonry structure has been the load-bearing effect, and the walling thermal property is poor, and thermal conductivity is high, if reach country's energy-conservation requirement of present stage, body of wall also need be done outer insulation, has so not only increased overall cost, but also has prolonged 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 the retaining wall materials'use, and this class building block quality is more crisp, and fragmentation destroys easily, 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 can effectively solve cement based building block cost height and the perishable problems that cause the building block of steel fiber feinforced cement base to affect concrete structure durability of invar muscle such as existing steel fiber, glass fibre, polypropylene fibre; The bearing wall material thermal property is poor also need do the problem that secondary insulation affects overall cost thereby can effectively solve; Can solve effectively that existing heat insulating building block resistance to cleavage is poor, intensity is low can only do the problem that the 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: at 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 with cotton stalk particle mass concentration, the cotton stalk particle that then will soak washes flush away alkali lye with clear water, dries as the cotton stalk siccative cotton stalk particle draining for subsequent use after flushing is finished; Second step: meter by weight takes by weighing respectively 240 parts to 320 parts in 80 parts to 120 parts of cotton stalk siccatives, 400 parts to 500 parts of cement, 1000 parts to 1500 parts in 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 the cement sand mixture, load weighted cotton stalk siccative is poured in the cement sand mixture to stir again, obtains just finished product mixture after stirring; The 4th goes on foot: load weighted water reducer is poured into be stirred into the water reducer aqueous solution in the load weighted water, mix in the finished product mixture at the beginning of the water reducer aqueous solution is poured into and obtain mixture; The 5th step: mixture is entered mould vibrate, the operation of vibrating obtains pattern after finishing, at the 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: at 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 with cotton stalk particle mass concentration, the cotton stalk particle that then will soak washes flush away alkali lye with clear water, dries as the cotton stalk siccative cotton stalk particle draining for subsequent use after flushing is finished; Second step: meter by weight takes by weighing respectively 240 parts to 320 parts in 80 parts to 120 parts of cotton stalk siccatives, 400 parts to 500 parts of cement, 1000 parts to 1500 parts in 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 the cement sand mixture, load weighted cotton stalk siccative is poured in the cement sand mixture to stir again, obtains just finished product mixture after stirring; The 4th goes on foot: load weighted water reducer is poured into be stirred into the water reducer aqueous solution in the load weighted water, mix in the finished product mixture at the beginning of the water reducer aqueous solution is poured into and obtain mixture; The 5th step: mixture is entered mould vibrate, the operation of vibrating obtains pattern after finishing, at the pattern surface coating, leave standstill after 24 hours form removal the building block of load bearing heat preserving anti-cracking cotton stalk cement based.
The below is the further optimization and/or improvements to the foregoing invention technical scheme:
