摘要
对掺加不同矿物掺和料的混凝土在不同龄期下的力学性能进行了试验研究。结果表明:当矿粉和粉煤灰复掺时,随着矿粉比例的增加混凝土的强度不断提高,以3∶1的比例复掺,其总掺量为20%时混凝土的强度最大;当矿粉和石灰石粉复掺时,两者的比例为3∶1、复掺量为10%时混凝土的强度最大;石灰石粉和粉煤灰复掺,两者的比例为3∶1、总掺量为30%时,混凝土的强度最小。
The effect of different mineral admixtures on the mechanics function of concrete was studied. The results show that, when mineral powder and fly ash are mixed, the strength of concrete increases along with the increase of the proportion of mineral powder, the proportion of mixed 3:1 complex, its total mixing content is 20%, the strength of concrete is the largest. When mineral powder and lime stone are mixed, a ratio of 3: 1, after mixing replace content is 10%, the concrete compressive strength is the largest. Lime limestone and fly ash after mixing, mixed ratio 3: l complex, the total content of 30% to replace, concrete compressive strength is the smallest.
