Embodiment 1

[0032] In the prior art, when mixing mortar and concrete, an appropriate amount of effective fine particles, generally about 25% of fly ash, is added to replace part of the sand and cement with the same amount of fly ash to improve the performance of the mixture. The principle is to make use of the activity of the mixed fly ash to allow the cement to effectively combine and react with fillers, admixtures, etc. during the mixing and hydration solidification process to produce a mixture with better workability and compactness. However, if the amount of effective fine particles in mortar and concrete is too much, it is easy to form powder coating on the surface of aggregate, cause retardation, increase shrinkage, weaken the effect of aggregate skeleton, and affect the compressive and flexural strength of concrete. While the early strength of the mixture increases, it will affect the later strength of the mixture. The present invention mainly utilizes the recycled stone powder pas...

Abstract

The invention relates to mixed mortar with a high content of stone powder paste. The mixed mortar with a high content of stone powder paste comprises the following components in parts by weight: 0.08-0.09 parts of water, 0.14-0.17 parts of cement, 0.3-0.31 parts of stone powder paste and 0.44-0.47 parts of sand. The mixed mortar with a high content of stone powder paste, provided by the invention,directly uses stone powder processed from sand and recovered by a concrete mixing system or on-site drilling as fillers, has a content of stone powder of more than 50% of all raw materials of stone powder paste mixed masonry mortar, and greatly reduces consumption of finished sand and water.

Description

technical field [0001] The invention relates to the field of comprehensive utilization of stone powder and plaster, in particular to a high-grade stone powder and plaster mixed mortar. Background technique [0002] In the field of comprehensive utilization of stone powder, there are mainly the following methods at home and abroad: 1. Use stone powder as the raw material for producing stone-like coatings (the proportion of stone powder raw materials in coatings is 70-80%), and stone-like coatings are used as high-grade products for architectural decoration. High price and profit; 2. As the raw material for producing stone powder bricks, the compressive strength of stone powder bricks produced by using inorganic strong polymerizing agent and high-pressure molding technology can reach 40MPa, but the production process is complicated and the price of polymerizing agent is high; 3. As Mixing concrete admixtures to produce high-flow, high-impermeability and high-strength high-perf...
