Full-machine-made sand masonry mortar taking limestone as aggregate and preparation method thereof
The invention discloses full-machine-made sand masonry mortar taking limestone as aggregate and a preparation method of the full-machine-made sand masonry mortar. The full-machine-made sand masonry mortar taking limestone as the aggregate is prepared from the following components in parts by weight: 130 to 150 parts of cement, 720 to 790 parts of limestone machine-made sand, 100 to 150 parts of limestone powder, 0.2 to 0.25 part of cellulose ether and 0.005 to 0.02 part of an air entraining agent, wherein the limestone machine-made sand and the limestone powder are prepared by crushing high-calcium stones, the fineness modulus of the limestone machine-made sand is 2.5, and the fineness modulus of the limestone powder is 0.07. The full-machine-made sand masonry mortar with limestone as theaggregate has the advantages of being good in workability, small in bleeding amount, capable of relieving shortage of natural sand resources due to the fact that limestone tailings serve as machine-made sand, good in heat preservation and insulation effect and durable.
本发明公开了一种以石灰石为骨料的全机制砂砌筑砂浆及其制备方法。以石灰石为骨料的全机制砂砌筑砂浆包括以下重量份的组分：130‑150份水泥、720‑790份石灰石机制砂、100‑150份石灰石粉、0.2‑0.25份纤维素醚、0.005‑0.02份引气剂；石灰石机制砂和石灰石粉由高钙石子粉碎制得，石灰石机制砂的细度模数为2.5，石灰石粉的细度模数为0.07。本发明的以石灰石为骨料的全机制砂砌筑砂浆具有和易性好，泌水量少，且以石灰石尾矿作为机制砂，缓解天然砂资源紧缺，保温隔热效果好且持久的优点。
