1. The concrete strength of the grass-roots level shall reach C25 or higher, the water-cement ratio shall be controlled below 0.50, the concrete slump shall be controlled within 70-100mm, and the concrete mixture shall be reduced as far as possible and the bleeding shall be controlled.
2. In order to ensure that the concrete mixture has sufficient fluidity and conducive to construction, it is recommended that concrete be added with proper additives.
3, base concrete should refer to the standard of high-quality concrete for vibration, pay attention to the precise size and reduce laitance production.
4. The hardener floor is preferably constructed at the same time as the concrete structure. If the same leveling layer is to be used at the same time, it is recommended that the leveling concrete be fine-grained concrete with a thickness of not less than 50 mm and a telescopic reinforcement mesh be considered.
5. Pay special attention to the corner parts of the primary concrete construction block to ensure that the concrete is vibrated and compacted and additional strengthening measures should be taken.
Construction Notes:
1. For the concrete setting time experiment, select the appropriate concrete mix ratio and cement admixture. The concrete is set too fast and the corundum surface cannot be constructed. The concrete is set too quickly and a large amount of cement slurry is squeezed upward to affect the surface quality during the emery construction.
2. Formulate reasonable concrete construction techniques to ensure the speed of continuous pouring and surface layer construction.
3. According to the requirements, choose a reasonable surface material, strictly control the material entering the market, and strictly prohibit the use of quartz sand instead of corundum to weaken the surface layer.
4. Select personnel with construction experience to carry out special level control and surface construction to ensure quality
5. Strengthen the sense of protection of finished products, especially the finished product protection of colored diamond flooring
EPDM o-rings, or ethylene propylene o-rings, are a family of synthetic elastomers with lower cost steam and chemical resistance, particularly for applications involving solvents, acids and other mild chemicals. our company has the largest inventory network of EPDM o-rings and made on demand custom manufacturing often without tooling fees, so the EPDM o-rings you need are always available. Whether it`s for water systems, braking systems, medical, pharmaceutical, food or dairy use, you can count on us to deliver your o-rings fast and efficiently.

EPDM O-Rings Summary:
Ethylene-Propylene rubbers make up a family of synthetic elastomers characterized by excellent chemical and thermal resistance. EPDM materials are most commonly used in applications involving solvents, acids, and other aggressive chemicals. EPDM has very poor compatibility with most mineral and petroleum based oils and is seldom used in those applications.
