Masonry mortar capable of being pneumatically conveyed
The invention provides masonry mortar capable of being pneumatically conveyed, which is formed by mixing premixed dry-mixed masonry mortar and water; wherein the premixed dry-mixed masonry mortar comprises the following components in percentage by mass: 12%-18% of cement, 16%-24% of powder, 56%-66% of 0-1.2 mm machine-made sand, 0-16% of 1.2-2.4 mm machine-made sand, 0.03%-0.055% of cellulose ether, 0.005%-0.015% of starch ether and 0.05%-0.1% of rubber powder, and the water addition amount during mixing is 15%-18%. The manufacturing process comprises the following steps: crushing high-purity limestone to obtain machine-made sand; respectively and accurately weighing the required contents of all the components to prepare the premixed dry-mixed masonry mortar; and uniformly mixing the premixed dry-mixed masonry mortar and water with a corresponding water adding amount to obtain the finished mortar. Compared with the prior art, high-quality machine-made sand is used, and grading can be well regulated and controlled; besides, high-floor pneumatic conveying can be effectively carried out on materials, wherein the materials are not separated or layered in the conveying process, raised dust is avoided, and waste water generated when traditional pumping equipment is used for conveying is not generated.
本发明提出了一种可气力输送的砌筑砂浆，由预拌干混砌筑砂浆和水混合而成，所述预拌干混砌筑砂浆各组分的质量分数如下：水泥12％～18％、粉料16％～24％、0～1.2mm的机制砂56％～66％、1.2～2.4mm的机制砂0～16％，纤维素醚0.03％～0.055％、淀粉醚0.005％～0.015％和胶粉0.05％～0.1％，混合时加水量：15％～18％，其制作过程包括如下步骤：采用高纯度石灰石破碎后得到机制砂；分别精确称量各组分所需的含量，制成预拌干混砌筑砂浆；将上述预拌干混砌筑砂浆和对应加水量的水进行混合处理，混合均匀后得到成品砂浆。与现有技术相比，使用高品质机制砂，级配具有较好可调控；本发明能有效的对材料进行高楼层气力输送，输送过程中材料不离析不分层，无扬尘，不产生传统泵送设备输送时的废水。
