Segregation of concrete is a phenomenon in which the cohesion between the components of the concrete mixture is insufficient to resist the sinking of the coarse aggregate, and the components of the concrete mixture separate from each other, resulting in uneven internal composition and structure. It usually manifests as the separation of coarse aggregate and mortar from each other, for example, dense particles are deposited at the bottom of the mixture, or coarse aggregate is separated from the mixture as a whole.
The hazards of segregation
It affects the performance of concrete pumping construction, causing sticky cans, pipe blockage, affecting the construction period, etc., and reducing economic benefits.
It affects the apparent effect of the concrete structure, with sand patterns, exposed aggregates, and exposed steel bars appearing on the surface of the concrete.
The strength of concrete will be greatly reduced, which will seriously affect the load-bearing capacity of the concrete structure, destroy the safety performance of the structure, and in severe cases will cause rework and huge economic losses.
Hydroxysulfonate-concrete segregation repair agent: This product is a new type of concrete segregation repair agent synthesized at high temperature using hydroxysulfonic acid as the main material. This product is very effective in solving the concrete segregation problem that occurs when the concrete arrives at the construction site. The functional improvement and coordination of large energy does not affect the fluidity and strength of concrete.
Instructions for use: After diluting 1 kilogram of this product with 10 kilograms of water, manually slowly (3-10 minutes) pour it into the mixing tank truck. The state of the concrete should be observed when adding, if the concrete state meets the construction requirements. No need to add anything later. </p
