Product introduction

Permeable concrete additive, also known as permeable concrete reinforcing agent and cementing material, is a reddish-brown transparent liquid. It is designed using advanced foreign synthesis technology and core-shell structure. It participates in the cement hydration reaction to form a high-molecular polymer cement hydration body, which can It is an additive that greatly improves the compressive and bonding strength of cement hydration bodies and improves the freeze-thaw resistance, durability and weather resistance of permeable concrete.

Features

FEM Permeable concrete additives are very effective in improving strength, reducing costs, increasing slump, extending operable time and coating thickness on the stone surface;

The thickness of the coating will not become thinner due to the increase in slump or most of it will fall to the bottom layer, and can be evenly wrapped on the surface of the stone;

Improve work efficiency and shorten project duration.

Product performance

It can solve the following problems: Low product strength.Bonded with cement and stones, the strength is as high as C15， Moreover, the water permeability is low, and increasing the amount of cement will result in impermeability.

Low water permeability. Increasing water permeability by reducing the amount of cement will result in a significant decrease in compressive strength.

Poor resistance to freezing and thawing. The unique gap structure of permeable concrete will make the permeable concrete more susceptible to freeze-thaw damage. After experiencing repeated freezing and thawing in winter, the permeable concrete will generally become a "permeable beach" if the stones are loose, falling off, crispy, and the project quality is serious in spring.

The surface layer of permeable concrete is efflorescent. Because the cement generates chlorine and alkaline after solidification, the white crystals that precipitate when exposed to water will adhere to the surface of the cement, seriously affecting the surface texture of the permeable concrete and affecting the acceptance of the project.

Poor performance. Permeable concrete bonded with cement and stones is in a semi-dry and loose state, with poor water retention and fluidity. Some have lost too much water and lost their solidification ability before being delivered to the construction site; some permeable concrete has poor fluidity after being delivered to the construction site, which greatly increases the difficulty and construction time of construction; some even lose water during the construction process. Too much water and loss of coagulation ability.

How to use and precautions

 FEM For permeable concrete additives, you only need to add about 10 kilograms per cubic meter to ordinary concrete to make highly permeable concrete;

The product should be stored in a cool, dry and ventilated place to avoid moisture;

Unopened materials have a shelf life of six months.
