本文主要对以原状粉煤灰和生石灰为主要原料制成的无熟料水泥（简称双灰粉）用作抹灰和砌筑砂浆，进行了砌体的力学性能试验，并给出了不同强度等级砂浆的配合比和砌体的抗压、抗剪强度及有关试验资料。采用水泥、双灰粉砂浆代替水泥白灰砂浆，每m~3可节约水泥45～95kg，每m~3降低材料费2．75～19．28元，具有较好的经济效益、社会效益和环境效益。
In this paper, the clinker-free cement made of fly ash and quicklime as the main raw materials is used as plastering and masonry mortar, and the mechanical properties of the masonry are tested, and different strengths are given. Grade mortar mix ratio and masonry compressive strength, shear strength and related test data. Using cement and double-ash mortar instead of cement-white mortar, cement can save 45 to 95kg per m~3, and reduce material costs from 2.75 to 19.28 yuan per m~3, with good economic, social, and environmental benefits. benefit.
