混凝土小砌块专用砂浆的生产与应用

混凝土小砌块的特性对砌筑和抹灰砂浆提出了特殊要求,通过试验确定专用砂浆的技术指标,提出了原材料质量、配合比设计、生产储存及质量控制等方面的要求,使专用砂浆具有良好的和易性、保水性和黏附性。在砌筑和抹灰工程应用中砂浆稠度控制、凝结时间满足施工要求,与混凝土小砌块粘结良好,强度满足设计要求,空鼓、开裂现象明显改善,施工质量得到保证。

Production and Application of Special Mortar for Small Concrete Blocks

The performance of small concrete blocks has raised special requirements of the masonry and floating mortar. Tests are conducted to determine the technical indices of the special mortar, and raise the requirements of the quality of raw materials, design of mix ratio, production storage, quality control, etc. make the special mortar good at workability, water retention and coherence. While applied in the masonry and floating works, the mortar meets the construction requirements in density control and setting time, with good coherence to the small concrete blocks and the strength to the design, hollows and cracks remarkably minimized and construction quality assured.
