Several Common Materials of Concrete Used in Wet Grouting Machine

HSP-5 type explosion-proof wet spraying machine through continuous technical transformation, can achieve significant improvement in the construction environment. HSP-5 explosion-proof wet sprayer can control the quality of concrete spraying and reduce the resilience of concrete. When spraying wet, because the proportion of water and cement is easy to control, the solidification degree of concrete is relatively high, which can improve the quality of spraying concrete and the uniformity of concrete to a certain extent. The HSP-5 type wet explosion-proof wet sprayer has the advantages of strong environment, small volume and convenient maintenance. It can manually hold the jet and use pneumatic conveying, which can effectively save users' production costs and improve production efficiency.

Following is the introduction of several kinds of concrete materials commonly used in HSP-5 explosion-proof wet sprayer.

1. 1.Fine aggregate. It can make the pump concrete mixtures have a great impact on the performance, the fineness modulus is best 2.3-3.0, using continuous gradation, in which the best particle size is less than 20% of the proportion of 0.315 mm fine aggregate.


2. 2.Additives. In the process of pumping, adding some water reducing agent or fly properly not only reduces the hydration heat of mass concrete, but also effectively improves the viscoplastic concrete and water retention.


3. 3.Coarse aggregate. The ratio of coarse aggregate to conveyor pipe diameter should be 1:3, which depends on the maximum diameter of the pipeline. A continuous gray scale should be adopted, and the content of flaky particles must be less than 10%.


4. 4.segregation of mixed concrete in the process of transportation, so often used cement, it has good water retention and water secretion, in general, the most commonly used Portland cement.
