高保水性砌筑水泥性能的研究

Performance Research on High Water Retention Masonry Cement

高保水性砌筑水泥是一种新型的专用水泥,其制备砂浆的性能与预拌砂浆相近,但能耗和成本较预拌砂浆低。研究了高保水性砌筑水泥及其砂浆的保水率、抗压强度、拉伸粘结强度和收缩性等性能,参考我国砌筑水泥和砂浆的相关标准,提出高保水性砌筑水泥的性能指标,为高保水性砌筑水泥广东省地方标准的编制提供依据。

The high water retention masonry cement is a new type of special cement, and the mortar made of it has the same performances as the ready-mixed mortar, while the energy consumption and cost of it can be reduced a lot. In this paper the water-retention, compressive strength, tensile bond strength and shrinkage ratios of high water retention masonry cement and mortar made of it are studied. And combined with the ready-mixed mortar standard and the masonry cement specifications, the performances indexes of high water retentive masonry cement are put forward as a reference for high water retention masonry cement standard of Guangdong Province.
