Environment-friendly concrete with high low-temperature carbonization resistance and preparation method thereof
The invention discloses environment-friendly concrete with high low-temperature carbonization resistance and a preparation method thereof, and relates to a novel building material. The invention aims to provide the environment-friendly concrete with high low-temperature carbonization resistance and the preparation method thereof, which can improve the strength and the stability of the concrete and solve the problems that industrial byproducts such as steel slag and rice hull ash pollute the environment, the early strength development of the concrete is slow in winter construction, the carbon dioxide corrosion is serious and the like. The invention relates to environment-friendly high-low-temperature-carbonization-resistance concrete which is prepared from, by weight, 100-500 parts of ground steel slag powder, 100-400 parts of metakaolin, 10-50 parts of modified rice hull ash, 10-30 parts of sodium hydroxide, 200-250 parts of water glass, 750-900 parts of ordinary sand, 850-1000 parts of pebbles and 10-60 parts of water.During preparation, solid components are placed in a stirring machine to be stirred for 30 s, water is mixed into the water glass to form a mixed solution, and the mixed solution is mixed with water to form the environment-friendly high-low-temperature-carbonization-resistance concrete. Adding sodium hydroxide into the mixed solution, stirring, dissolving, cooling, placing, inverting the placed and cooled mixed solution into a stirrer, and stirring for 2 minutes to obtain a finished product.
本发明一种环保高抗低温碳化混凝土及其制备方法涉及一种新型建筑材料。其目的是为了提供一种能够提高混凝土的强度及稳定性，同时解决钢渣、稻壳灰等工业副产物污染环境，在冬季施工混凝土早期强度发展慢，二氧化碳腐蚀严重等问题的环保高抗低温碳化混凝土及其制备方法。本发明一种环保高抗低温碳化混凝土，以重量份数计，包括磨细钢渣粉100～500份，偏高岭土100～400份，改性稻壳灰10～50份，氢氧化钠10～30份，水玻璃200～250份，普通砂750～900份，石子850～1000份，水10～60份，制备时，将固体成分置于搅拌机中搅拌30s，将水混入到水玻璃中形成混合溶液，再将氢氧化钠加入到混合溶液中并搅拌溶解冷却放置，将放置冷却后的混合溶液倒置搅拌机中，搅拌2min后即可获得成品。
