The Requirement on the quality of industrial floors, floor repair, road work, basement & stilt parking area have become more exacting and demanding during the last few years.A high quality concrete floor requires not only to be level but it should also have high wear resistance, high compressive strength, reduce shrinkage, minimum water permeability & minimum dusting.
The Vaccum Dewatering System TREMIX is for laying high quality concrete floors where the cost being very economical. The compressive strength of vaccum treated concrete at the age of 28 days is 30 to 60% higher than that of normal concrete
The key to the use of this method is the dewatering of concrete by vacuum process where surplus water from the concrete is removed immediately after placing and vibration, reducing the water: cement ratio to an optimum level. Therefore, adopting the Vaccum Dewatering Flooring method facilitates use of concrete with better workability than what is normally possible. A lowered water to cement ratio due to vacuum dewatering leads to improvement in each of the concrete properties.
