Modifier for concrete, counterweight concrete as well as preparation method and application of modifier
The invention relates to the technical field of building materials, in particular to a modifier for concrete, counter weight concrete and a preparation method and application of the counter weight concrete. The modifier for concrete comprises the following raw material components in parts by weight: 50-80 parts of a polycarboxylate superplasticizer; 3-8 parts of an organic silicon reinforcing agent; and 12 to 38 parts of redispersible latex powder. On the basis of the steel slag, the iron ore and the cement, the modifier is doped, so that the obtained counterweight concrete not only can reduce the use amount of water and cement with low apparent density, but also can reduce the use amount of the iron ore with high apparent density, the apparent density of the finally obtained counterweight concrete reaches 3.3-3.5 g/cm < 3 >, the strength grade reaches C30-C60, the slump is 180-220mm and the construction requirements of house building foundations can be met.
本发明涉及建材技术领域，特别涉及一种用于混凝土的改性剂、配重混凝土及其制备方法和用途。一种用于混凝土的改性剂，包括下列重量份的原料组分：聚羧酸减水剂50～80份；有机硅增强剂3～8份；可再分散性乳胶粉12～38份。本申请通过在钢渣、铁矿石和水泥的基础上，掺入改性剂，获得的配重混凝土不仅能减少低表观密度的水和水泥的用量，而且还能减少高表观密度的铁矿石的用量，最终得到配重混凝土的表观密度达到3.3～3.5g/cm3，强度等级达C30～C60，塌落度为180～220mm，能满足房屋建筑基础的施工要求。
