摘要/Abstract

摘要： 本文从陶粒泡沫混凝土的成型方式出发,研究了陶粒预处理方式、陶粒掺入方式、拌合水加入方式等对陶粒泡沫混凝土工作性能、干湿密度、抗压强度、抓底性能、陶粒分布的影响,确定陶粒泡沫混凝土最佳成型方式。结果表明,采用陶粒饱水预处理方式和拌合水分两次加入的方式可以有效提高浆体扩展度。不同的成型方式对于陶粒泡沫混凝土的骨料扩展度影响较小。陶粒掺入方式和拌合水加入方式均影响陶粒泡沫混凝土的干湿密度。拌合水分两次加入方式和陶粒湿混掺入方式有利于提高陶粒泡沫混凝土的抗压强度。陶粒预处理方式决定抓底性能,同时拌合水加入方式也影响抓底性能。

Abstract: Based on the forming methods of ceramsite foam concrete, this paper studied the influences of the pretreatment method of ceramsite, the incorporation method of ceramsite and the adding method of mixing water on the work performance, dry and wet density, compressive strength, bottom grip performance and ceramite distribution of ceramsite foam concrete, and determined the optimal forming methods of ceramsite foam concrete. The results show that slurry expansion degree can be effectively improved by the saturated water pretreatment method of ceramsite and the method of adding mixing water twice. Different forming methods have little influence on the aggregate expansion degree of ceramsite foam concrete. The dry and wet density of ceramsite foam concrete is affected by the incorporation method of ceramsite and mixing water. The adding method of mixing water twice and wet mixing of ceramsite are beneficial to improve the compressive strength of ceramsite foam concrete. The pretreatment method of ceramsite determines the bottom grip performance, and the adding method of mixing water also affects the bottom grip performance.

Key words: ceramsite foam concrete, forming method, work performance, compressive strength, bottom grip performance
