Novel cement-based plastering mortar construction method

Abstract

The invention discloses a novel cement-based plastering mortar construction method including the steps of construction preparation, base layer treatment, primary wall surface plastering and leveling, spraying of appropriate amount of water on a wall surface, mortar preparation, mortar plastering on a wall, final wall surface plastering and leveling, compacting and troweling. The mortar preparation includes: pouring water into a stirring barrel prior to pouring cement plaster into the stirring barrel according to the ratio of the cement plaster to the water of 1:0.18, and stirring for 2-3 minutes to enable mortar to reach proper thickness. The final wall surface plastering and leveling includes: roughly plastering and leveling one layer of mortar after the mortar is plastered on the wall, and then carefully plastering and leveling the mortar. The novel cement-based plastering mortar construction method has the advantages that mortar bonding strength is high, water resistance is excellent and the like; the method is applied to finish and base layer treatment of wall surfaces in indoor damp water seepage environments, smooth wall surfaces, cement-poured wall surfaces and ceiling plastering surfaces of various high-rise buildings; the finished wall surfaces are prevented from mortar peeling, cracking and shedding after being affected with damp and in the presence of water, the bonding strength of the finished wall surfaces and the base layer are high, and the method is convenient and rapid to use; the finished wall surfaces are smooth, level, non-poisonous and odorless.

Description

technical field [0001] The invention belongs to the application field of building materials, and in particular relates to a construction method of a novel cement-based plastering mortar. Background technique [0002] Plastering mortar is widely used as a common dry-mixed mortar. Plastering in general civil buildings has an internal surface plastering of 3-5rri2 per square meter of construction area, and an external plastering of 0.15-0.75rri2. The cost of plastering accounts for about 10% to 15% of the total construction cost, and about 30% to 40% of the total construction period in terms of construction period. earth influence. In the actual construction process, problems such as poor workability and cracking of plastering mortar often occur. When producing plastering mortar, most of the raw materials used are natural minerals, which makes the production cost high. In terms of utilization of industrial waste residues, often due to the low activity of industrial waste resi...
