The vacuum concrete method involves covering the surface with a vacuum mat immediately after concrete placement and using a vacuum pump to remove some of the water from the concrete while simultaneously applying pressure to the concrete due to atmospheric pressure. Concrete treated with the vacuum method achieves increased compressive strength, tensile strength, and surface hardness compared to normally finished concrete. 【Features】 ■ In slabs, it is possible to increase density, improve waterproofing, reduce porosity, and enhance abrasion resistance. ■ It has significantly higher strength than normally finished concrete with a shorter curing period. ■ It has high initial strength, increased long-term strength, abrasion resistance, and freeze-thaw resistance, reduces hardening shrinkage, and enhances water tightness. *For more details, please download the PDF or feel free to contact us.
