本文对自燃煤矸石粉砂砌筑砂浆的可行性进行了初步探索.通过试验发现,使用煤矸石粉砂砌筑砂浆的基本性能满足工程上的一般要求.由于煤矸石粉砂本身具有一定的活性,因此,该砌筑砂浆比同体积配比的黄砂砌筑砂浆性能好,不必掺用石灰或多掺水泥同样可以满足沉入度、强度和保水性等要求,起到了节约水泥的作用. This article has carried on the preliminary exploration to the feasibility of self-igniting coal gangue silt mortar. Through the experiment, it is found that the basic performance of using gangue silt mortar to meet the general requirements of the project. Because the gangue silt itself has a certain Activity, therefore, the masonry mortar performance than the same volume ratio of yellow sand masonry mortar, do not have to use lime or mixed cement can also meet the submergence, strength and water retention requirements, played a cement effect.
