C20 equipment basic concrete 7 days can install equipment
For this problem, it is impossible to generalize and say that you can install or not install. It depends. The concrete strength growth is directly related to the cement, concrete strength grade, environment temperature and curing condition of concrete. If local temperatures above 20 degrees, curing condition is good, use normal manufacturer or early strength cement, cement can basically meet the design strength of 70% - 80%. Whether can according to the equipment, but also with reference to the requirements of equipment specifications, some equipment requirements, the foundation concrete strength of 70% can be installed, some equipment must reach 100% design strength to install

Concrete, referred to as "concrete", refers to the general term of a composite of composite materials, which are consolidated into a whole. Generally speaking, concrete is used to make cement, sand and stone. With water (containing additive and admixture) according to certain proportion coordination, classics agitate for cement concrete, also known as the common concrete, it is widely used in civil engineering. Concrete is one of the most important civil engineering materials in modern times. It is made of gelled material, granular aggregates (also known as aggregate), water, and when it is necessary to join admixtures and admixtures according to certain proportion, after even mixing, compacted molding, maintenance and hardening and become a kind of artificial stone. The concrete is rich in raw materials, low price and simple production process, so the usage is increasing. The concrete also has the characteristics of high compressive strength, good durability and wide range of strength. These characteristics make its use range is very wide, not only used in a variety of civil engineering, is the shipbuilding industry, machinery industry, the development of ocean, geothermal engineering, concrete is also important material.
