With the rapid development of the world economy, people pay more attention to energy conservation and environmental protection on the basis of meeting the needs of life, and pay attention to the long-term use of energy. The problem of insufficient energy
Foam concrete is foamed cement. Cement will use some admixtures in the foaming process. These admixtures mainly involve foaming agents, foam stabilizers, water reducers, anti-cracking agents, water repellents, etc. The use of the foam concrete outer edge
Block classificatioBlocks are artificial blocks made of concrete, industrial waste (slag, fly ash, etc.) or local materials. They are larger in size than bricks, have the advantages of simple equipment and fast masonry speed, and are in line with the indu
Polyvinyl alcohol (PVA) fiber is a fiber with high modulus of elasticity, high tensile strength and high alkali resistance, and has been widely used in cement-based reinforcements. The research indicates that PVA fiber has good dispersibility in cement co
From the perspective of the cost and usage of the materials, the foam concrete can better meet the engineering quality requirements during the construction process, and can also make various construction materials according to the shape of the molding die
Muffling grease is different from low-noise grease, although both are designed to reduce mechanical noise, but low-noise grease is the noise that reduces its own composition, while muffling grease directly reduces or eliminates mechanical noise.
