Abstract

The walls of the building often exhibit moisture problems as a result of exposure to rain and water absorption in the soil. Unfortunately, conventional concrete blocks purchased on the market have a high coefficient of capillary suction and a low resistance to water penetration. In this research, concrete blocks and cylinders were produced and analyzed experimentally. They were manufactured with washed concrete sand, type I Portland cement, paraffin wax and a 0,40 water-to-cement ( w/c ) ratio by weight. Blocks and cylinders were analyzed first without the addition of paraffin wax and then with the addition of 10 %, 20 %, 30 % and 40 % of paraffin wax by weight of the cement. Capillary water absorption test and resistance to water penetration test were completed. A comparative analysis of the results was performed in order to determine the optimum addition of paraffin wax. It was determined that the blocks with paraffin wax have better properties than conventional blocks without additives. Furthermore, it was concluded that the blocks with paraffin wax reduce moisture problems in the walls since these blocks have a low coefficient of capillary suction

石蜡乳液混凝土砌块
由于暴露在雨水和土壤中的吸水性,建筑物的墙壁经常出现水分问题。不幸的是,在市场上购买的传统混凝土砌块具有高的毛细吸力系数和低的透水阻力。在本研究中,制作了混凝土砌块和圆柱体,并对其进行了实验分析。它们是用洗涤过的混凝土砂、I型硅酸盐水泥、石蜡和按重量计为0.40的水灰比(w/c)制造的。首先在不添加石蜡的情况下分析块体和圆柱体,然后添加按水泥重量计10%、20%、30%和40%的石蜡。完成了毛细管吸水性试验和耐水渗透性试验。对结果进行比较分析,以确定石蜡的最佳添加量。经测定,添加石蜡的嵌段比不添加添加剂的传统嵌段具有更好的性能。此外,得出的结论是,含有石蜡的砌块减少了墙壁中的水分问题,因为这些砌块的毛细吸力系数较低
