PHC pipe pile concrete and preparation method thereof

Abstract

The invention relates to PHC pipe pile concrete, characterized by being prepared from the following components: a binding material, a synergist, fine aggregate, coarse aggregate, a water reducer and water, wherein the volume-weight of the concrete is 2400-2600Kg / m<3>, in each cubic meter of concrete, the dosage of the used binding material is 12-22 percent, the dosage of the synergist is 1.0-5 percent, the dosage of the fine aggregate is 22-32 percent, the dosage of the coarse aggregate is 40-52 percent, the mixing amount of the water reducer is 0.2-1.0 percent, and the dosage of the water is 4.0-7.5 percent. By mainly aiming at the defect of the existing PHC pipe pile concrete preparation technology, the invention provides a technology for preparing the concrete by completely replacing natural sand with low-grade machine-made sand, so as to solve the problems that the natural sand resource is scarce, and the low-grade machine-made sand resource is wasted and pollutes the environment.

Description

technical field [0001] The invention relates to concrete, in particular to a PHC pipe pile concrete and a preparation method thereof, belonging to the technical field of concrete production and processing. Background technique [0002] With the rapid development of my country's infrastructure construction, PHC pipe piles are more and more widely used in the construction field. At the same time, the requirements for the strength and performance of PHC pipe pile concrete in building foundation engineering are getting higher and higher. Sand is an essential component in the preparation of PHC pipe pile concrete. At this stage, most pipe pile enterprises in my country use natural sand for concrete production. However, with the long-term mining of natural sand, the resources of natural sand are also being exhausted day by day, and the mining has also caused serious pollution and damage to the environment. The national standard GB13476-2009 clearly stipulates that artificial san...
