在建筑工程中,建筑材料中石灰迄今还被广泛应用。然而,石灰在其生产、贮运和使用过程中,由于工序复杂,操作技术难度大,容易污染环境,影响人们的健康,近年来开始使用的袋装石灰粉,由于价高技术难度大,工程质量难以保证,所以无论是袋装熟石灰粉或生石粉普遍难以推广。 哈尔滨宾县新型建材厂研制生产的JHS型石灰晶,该产品通过了黑龙江省建设委员会的认证,袋装石灰晶每袋200克乳白色粉状,用石灰晶代替石灰制作建筑水泥混合砂浆,在同等条件下,1kg石灰晶可代替300kg石灰,同时改善了砂浆的和易性,抹灰层与墙体粘结强度提高,技术经济和社会综合效益显著。
In building engineering, lime has been widely used in building materials. However, in the process of production, storage, transportation and use of lime, due to the complexity of the process, the difficulty in operation technology, the environmental pollution, and the health of people, the bag lime powder that has been used in recent years is difficult due to high technical costs. The quality is difficult to guarantee, so it is difficult to popularize either packed lime powder or rock powder. The JHS type lime crystal developed and produced by Harbin Binxian New Type Building Material Factory has passed the certification of the Heilongjiang Provincial Construction Committee. The bagged lime crystals are 200 grams of white powder in each bag. The lime cement is used instead of lime to make the cement mortar for cement construction. Under the conditions, 1kg of lime crystals can replace 300kg of lime, and at the same time, the workability of the mortar is improved, the adhesion strength between the plaster layer and the wall is improved, and the technical, economic and social benefits are significant.
