【摘要】 研究了Ｃ３５级高掺量粉煤灰泵送混凝土在大体积混凝土基础中的应用问题．该混凝土中４２５号普通硅酸盐水泥用量为３３０ｋｇ／ｍ３，粉煤灰掺量为１３０ｋｇ／ｍ３，结果表明：采用该技术不仅混凝土强度在６０ｄ龄期可达Ｃ３５要求，而且可以明显降低混凝土的温升并推迟温峰出现的时间．更多还原

【Abstract】 The application of C35 pumping concrete with high content fly ash in the mass concrete construction was studied.The content of 425 P.O cement in this concrete is 330 kg/m 3,and fly ash is 130 kg/m 3.The results show that by using this technology,the concrete can meet the requirement of C35 in 60 days,particularly,the heat rise of the mass concrete can be reduced obviously,and the appearance of heat peak can be deferred.更多还原
