针对矿物掺和料与水泥砂浆相关性能(抗拉强度、抗压强度)的关系展开研究。首先交待试验的各种材料及规格-水泥、拌和水、拌和砂、掺和料、化学成分,固定相应成分,变化掺合料设计6种试验样本,在相同条件下进行养护,定期测量水泥砂浆样本的抗拉强度、抗压强度、脆性系数,记录分析。通过图形形式,重点分析矿物掺合料对抗压强度、脆性系数的影响,最后得到粉煤灰可以有效降低水泥砂浆的脆性系数,对于多种矿物掺合料的情况,多种矿物掺合料水泥砂浆的脆性系数降幅大于单一矿物掺合料水泥砂浆脆性系数降幅。
The relationship between mineral admixtures and cement mortar properties (tensile strength, compressive strength) was studied. First of all, to test the test of various materials and specifications - cement, mixing water, mixing sand, admixture, chemical composition, the corresponding composition of fixed, changing admixture design six kinds of test samples, under the same conditions for conservation, regular measurement of cement mortar Tensile strength, compressive strength, brittleness coefficient, record analysis of samples. Through the graphical form, focusing on the impact of mineral admixtures on the compressive strength and brittleness coefficient, finally obtained fly ash can effectively reduce the brittleness coefficient of cement mortar. For a variety of mineral admixtures, a variety of mineral admixtures The brittleness coefficient of cement mortar decreased more than that of single mineral admixture cement mortar.
