根据水泥基材料强度与水灰比定律:水泥基材料的强度之比与水灰比成一次函数,用实验方法建立起水泥用量和养护龄期与再生微粉砂浆强度的关系式,以此为基础分别研究砂浆中水泥、自配固化剂LQ1、LQ2添加量、砂浆养护龄期与抗压强度的关系式。并采取随机实验对固化剂LQ1、LQ2固化砂浆的关系式进行检验和修正,得到LQ1、LQ2固化再生微粉砂浆强度增长模型的有效预测模型。
Based on the strength of cement-based materials and the law of water-cement ratio, the ratio of the strength of cement-based materials to the water-cement ratio is a linear function. Based on this, the relationship between cement consumption and age of recycled mortar is established by experimental methods The relationship between cement, self-mixing curing agent LQ1 and LQ2, mortar curing age and compressive strength were studied respectively. The relationship between curing agent LQ1 and LQ2 curing mortar was tested and corrected by random experiments. The effective prediction model of the strength growth model of LQ1 and LQ2 cured regenerated powder mortar was obtained.
