Abstract

The invention discloses a formula of water-proof dry-mixed mortar. Materials in the formula comprise aggregates and additives, wherein the aggregates comprise cement, water and sand; the additives comprise a water reducing agent, an expanding agent, a water repellent, latex powder and a cellulose ether; the mixing ratios of the aggregates in the water-proof mortar are as follows: the water-cement ratio is 0.487:1, and the cement-sand ratio is 1:2.5; the mixing amounts of the additives relative to the cement are respectively 0.825% of the water reducing agent, 8% of the expanding agent, 0.25% of the water repellent, 0.44% of the latex powder and 0.6% of the cellulose ether. The formula is clear and simple, the mixing of the dry-mixed mortar is extremely convenient, and the water-proof and seepage-proof properties of the product are great.

Description

technical field [0001] The invention relates to the field of dry-mixed mortar, in particular to a formula of waterproof dry-mixed mortar. Background technique [0002] During construction, after pre-mixing sand, cement and other additives in the factory, they can be used directly during construction, which can avoid the waste of manpower, material resources and space on the construction site for on-site mixing, and effectively improve the efficiency of construction. The existing dry-mixed mortar products are easy to get wet when used in construction. In order to overcome these problems, we have formulated a waterproof dry-mixed mortar. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the dry-mixed mortar is not waterproof, and to provide a formula of waterproof dry-mixed mortar. [0004] In order to achieve the above object, the present invention provides a formula for waterproof dry-mixed mortar. The raw materials of th...
