Square pile high strength concrete

Abstract

A square pile high strength concrete relates to the manufacture technology of a concrete square pile, in particular to the preparation technology of the concrete thereof. The concrete of the square pile per cubic meter comprises the following components by weight percent: 1250 to 1350kg of pebbles, 650 to 680g of yellow sand, 9.8 to 10.2 kg of water reducer, 310 to 330 kg of cement and 135 to 145 kg of ganister sand. The mass content of SiO2 in the ganister sand is more than or equal to 95 percent. The specific surface area of the ganister sand is 4000 to 5000 cm2 / g. The invention replaces 20 to 35 percent of cement with the ganister sand in equal amounts to manufacture the prestressed high strength concrete square pile. The performance of the obtained square pile with the ganister sand and the square pile concrete thereof reaches or exceeds the performance of the traditional square pile without blending the ganister sand and the concrete thereof. The invention can improve the alkalinity of the concrete, is favorable for the alkalic protection of reinforcing bars and can reduce the manufacture cost.

Description

technical field [0001] The invention relates to the production technology of concrete square piles, especially the preparation technology of concrete. Background technique [0002] Concrete square piles are an important part of building foundations, and high-strength concrete square piles are the basic guarantee for building quality. In the current concrete square pile, the weight of each raw material per cubic meter of concrete is: 1250kg-1350kg of stones, 650kg-680kg of yellow sand, 460kg-480kg of cement, 9.8kg-10.2kg of water reducing agent, and the rest is water. The cost price of a cubic meter of concrete material is 260-290 yuan, and its strength can only reach C 80 standard. Therefore, existing concrete square piles have the defects of high price and low strength, can not adapt to the requirements of economical production, and can not be suitable for occasions with high strength requirements. [0003] Most of the sand distributed in nature is mixed sand, and there ...
