Concrete is one of the present age most important civil engineering material.It is by cementitious material, granular aggregat, water, with
And the additive and admixture added if necessary is prepared by a certain percentage, through uniform stirring, closely knit shaping, maintenance hardening forms
A kind of artificial stone material.The characteristics of concrete has abundant raw material, cheap, simple production process, thus make its dosage more next
It is bigger.Concrete also has the features such as compression strength is high, and durability is good, and strength grade scope is wide at the same time.These features make it
It is quite varied with scope, not only used in various civil engineerings, be exactly shipbuilding industry, mechanical industry, the exploitation of ocean, ground thermal technology
Journey etc., concrete are also important material.
Pile pile is divided into post-tensioned prestressing stake and pretensioned-prestressed tube pile, prestressed concrete pipe pile (PC pile piles) and
Thin tubular piles produced by prestressed concrete (PTC pile piles) and high strength prestressed concrete pipe pile (PHC pile piles).Due to the property of concrete
It can determine the performance after the completion of pile pile manufacture, therefore, in the manufacture of prefabricated tubular pile, related raw material matches somebody with somebody in concrete
Than critically important.
Existing concrete is mostly using cement, sand, the manufacture of stone mixing water, when material fiting ratio is unreasonable, coagulation
Native surface is easily cracked, and tensile strength is not high, and corrosion resistance is poor, and impermeability is poor.
So we want right combination to consider the formula of concrete, not only to meet certain coefficient of pushing aside, but also to examine
Consider because increase sand coarse aggregate ratio and caused by concrete strength reduction.
