Manufacturers of permeable concrete admixture manufacturers, the performance of permeable concrete technology can put themselves in the position of the other side, rationally analyze the reasons for failure, help the other side to restore self-confidence, out of the shadow, that is the person to do big things.
Main technical performance
1. Strengthening and strengthening effect: Under the premise of the same concrete slump and equal cement dosage, the water reduction rate can be ≥25%, the early strength of concrete can be significantly improved, and the strength of 1-3 days can be increased by ≥75%. Greatly improve the various mechanical properties of permeable concrete.
2. Bonding and cohesive properties: The surface of ecological concrete is rough and porous, and the general porosity is about 30%. The product has strong cohesive cohesion, can effectively bond cement, sand and stone tightly together, and forms pores under the premise of design strength, forming the purpose of rapid water permeability.
3. Anti-freeze durability function: This product can enhance the anti-freeze durability of ecological concrete and reduce the strength loss of ecological concrete.
4, the operation and workability is excellent: construction is convenient, no need to vibrate. It only needs to flatten the ecological concrete according to the thickness of the design, the surface is smoothed, no need for maintenance, and it has very remarkable operability and work efficiency.
5, environmental performance: odorless, non-flammable, harmless to human health, no pollution to the environment.
product description
This product is a special additive designed and developed by the company for cement-based permeable floor.
Pervious concrete consists of single-stage crushed stone, high-strength Portland cement and water. It has high porosity, high bearing capacity and low plasticity. The reinforcing agent has the advantages of lowering the water-cement ratio, enhancing the cohesive property and improving the volume stability. The characteristics ensure the physical structure of the high porosity of the permeable concrete and the mechanical properties and durability of the high bearing capacity to meet the function of use. The technical performance reduces the water-cement ratio, improves the strength of the permeable concrete, and the highest strength can reach the strength level of C40.
Enhanced adhesion and concrete volume stability. Improve impact resistance and wear resistance. Improve the durability of concrete. Application technical points This product is blended into the concrete according to the amount of cement 3-5%, and the dosage is adjusted according to the state of the concrete. Generally, the water-cement ratio is preferably 0.3-0.4.
If the concrete cohesive performance is not good, the cement brand should be replaced. The cement should be made of Portland cement or ordinary Portland cement. It is not suitable to use slag cement, fly ash cement and composite cement.
The newly-mixed permeable concrete material should be paved in time to prevent the rapid increase of moisture. In the hot and dry climate, the amount of the reinforcing agent should be increased in an appropriate amount, and the plastic film should be covered for 7-14 days. Packing and Storage This product is packaged in a plastic film lining with a standard of 25 kg/bag. It can also be packaged according to the specific measurement required by the user. It should be placed in a dry and cool place and stacked on a wooden pallet. The shelf life of this product is 24 months, and the overdue period should be tested before passing the test.
