A metering pump is a pump used to pump liquids at adjustable flow rates which are precise when averaged over time.

Foam concrete, the basic raw material for cement, lime, water, foam, on the basis of adding some packing, aggregate and admixture.

Foam concrete in the process of transportation, vibrating, pumping appear coarse aggregate sinking, exudation water floating phenomenon known as concrete.

Foam concrete as a kind of new building materials, widely used, to say the technological progress rapidly, current Japan already has a more advanced preparation technology of concrete.

Foam concrete as a new environmental protection building materials (why do we put the foam concrete as a new type construction material?)

Compared with the foreign foam concrete application scope, the application of the domestic is "very weak", foam concrete application is relatively widely abroad, main areas of application include: retaining wall, the runway arena, composite wall, backfi

Concrete hydration reaction is increased with time and gradually improve, under normal maintenance in the first seven days compressive strength is growing rapidly

Cement strength grade is used to represent the cement strength of high and low level, it is to put the cement and move in a ratio of 1:3

A wide variety of cement strength is different also, all kinds of performance is also different, different varieties of cement with different cement
