Abstract

The invention provides a special reinforcing agent for ready-mixed pervious concrete and a preparation method thereof. The special reinforcing agent for the ready-mixed pervious concrete includes thefollowing raw materials by mass: 40-45% of anti-cracking component, 20-25% of flexural component, 2%-4% of thickening component, 19-24% of adhesive component and 10-15% of water reduction component. The dosage of the special reinforcing agent in the pervious concrete is 2-3% of the mass of a cementing material. The reinforcing agent can not only effectively prevent the late shrinkage of the pervious concrete and reduce the stress cracking, but also significantly improve the flexural resistance and the frost resistance of the pervious concrete, ensures the mechanical property and the durabilityof pervious concrete pavements, and enhances the water retention and the slump retention of the previous concrete to meet the construction requirements of the ready-mixed concrete. The reinforcing agent is beneficial to prepare the premixed medium and high strength pervious concrete.

Description

technical field

[0001] The invention belongs to the field of auxiliary agents for building materials, and in particular relates to a reinforcing agent for ready-mixed permeable concrete and a preparation method thereof. Background technique

[0002] With the rise of "sponge city" construction, the permeable concrete made of permeable concrete admixture has good compressive strength and good water permeability, which solves the environmental protection of the city well, improves the function of the urban ecosystem and reduces the urban The occurrence of flood disasters. The existing pervious concrete technology changes the structure of the concrete due to the pores between the stone aggregates, and is prone to shrinkage and fracture in the later stage. At the same time, the flexural strength of the permeable concrete is not enough, and it is also prone to fracture, which affects the mechanical properties of the concrete. Persistence. On the other hand, the low construction ...
