Abstract

The invention relates to the cement field containing slag, in particular to slurry for grouting an interlocking concrete block. The slurry for grouting the interlocking concrete block comprises 10-25 parts of concrete by weight and is characterized in that the slurry also comprises 50-70 parts of fine aggregate and 15-40 parts of mineral blend by weight, wherein the fine aggregate is obtained by mixing coal slag and aggregate chips uniformly according to any ratio; and the mineral blend is obtained by mixing coal ash and slag micro-powders uniformly according to any ratio. According to the slurry for grouting the interlocking concrete block, labor intensity is relieved; working efficiency is improved; construction cost is reduced; and the land resource is saved.

Description

technical field [0001] The invention relates to the field of slag-containing cement, in particular to a hole-filling slurry for concrete formwork blocks. Background technique [0002] With the increase of our country's population and the sustained and rapid economic development, construction projects in various places are in the ascendant and showing a momentum of vigorous development, so the demand for building materials is also increasing. The current building materials such as bricks require a large amount of cultivated land resources to be manufactured, consume a lot of energy, and cause serious environmental pollution. They cannot adapt to my country's sustainable development strategy, nor do they conform to my country's basic national policy of strengthening ecological construction and environmental protection. Contents of the invention [0003] In order to overcome the defects of the prior art and provide a building material with low energy consumption, little impac...
