Abstract
The invention provides waterproof waste-stone-powder dry-mixed mortar. A powder waterproof agent and waste stone powder are added into the dry-mixed mortar formula. The waterproof waste-stone-powder dry-mixed mortar comprises, by weight, 28 parts of cement, 16 parts of waste stone powder, 39 parts of sand, 5 parts of powder waterproof agent, 4 parts of redispersible rubble powder, 1 part of polyvinyl alcohol, 1 part of naphthalenewater reducer, 4 parts of cellulose fibers and 2 parts of polypropylene fibers; the powder waterproof agent comprises, by mass, 48% of calciumstearate, 35% of zincstearate, 7% of organosilicone powder water repellent agent and 10% of calciumhydroxide; the waste stone powder is a mixture of one or two of waste marble powder and waste granite powder and comprises, by mass, 35% of waste stone powder with the grain size smaller than 100 microns and 65% of waste stone powder with the grain size of 100-500 microns. According to the dry-mixed mortar, as the powder waterproof agent is added, the waterproof performance is good; as the industrial-waste waste stone powder is added, cost is reduced, and the dry-mixed mortar can be applied to constructional engineering.
Description
technical field [0001] The invention belongs to the field of building materials and relates to a waterproof waste stone powder dry powder mortar. Background technique [0002] Dry powder mortar, also known as dry-mixed mortar, is a mortar product with stable performance that is produced in the enterprise by adding different admixtures and various admixtures and mixing with aggregate and cementitious materials. It can be packaged and distributed uniformly. Products that are directly used by construction workers at the site of the construction project. Waterproof dry powder mortar is to compound waterproof components in the formula of general dry powder mortar to achieve the purpose of waterproofing. There have been many related researches. The polymer powder composed of formic acidacrylate, acetic acidacrylate, n-butyl acrylate and methyl methacrylate achieves the purpose of waterproofing; the Chinese invention patent "A Waterproof Dry PowderMortar" (patent application nu...
