Problems solved by technology

[0003] For hollow square piles, the quality of concrete is very important, and with the popularization and application of commercial concrete and high-strength concrete in our country, the durability and safety of concrete have received more and more attention, and the most used Concrete tends to leak due to shrinkage and cracking, reducing its functionality and durability

Embodiment Construction

[0009] Table 1 is the concrete preparation formula in the prior art and the concrete preparation formula of the present invention.

[0010] Below in conjunction with the preparation formulas of Table 1 and Table 2, do a detailed description. In the existing technology, the proportioning of each component when preparing concrete is: cement 320kg, mineral powder 60kg, fly ash 60kg, admixture 6.2kg, water 190kg, sand 724kg, gravel 1020kg. When using the preparation formula of this method to manufacture concrete of the same quality, the proportioning of each component is: cement 281kg, mineral powder 60kg, fly ash 60kg, admixture 5.65kg, water 185kg, sand 734kg, crushed stone 1053kg, CTF Concrete synergist is 2.41kg. It can be clearly seen from the two different proportions of ingredients that after adding CTF concrete synergist, the amount of cement required is significantly reduced, which solves the cost.

Abstract

The invention relates to a concrete making formula. The formula mainly comprises the following components, by weight, 270-290 parts of cement, 55-65 parts of mineral powder, 55-65 parts of coal ash, 5-6 parts of an additive, 180-190 parts of water, 725-745 parts of sand, 1040-1060 parts of broken stone, and 2-3 parts of a CTF concrete synergist. The formula has the advantages of concrete material workability improvement, water segregation reduction, small pumping friction resistance, reduction of 10-15% of the application amount of cement, and realization of maintaining or exceeding a reference strength, and a product obtained in the invention has the advantages of non-toxicity, no pollution and no production discharge, and is a green environmentally-friendly building material.

Description

technical field [0001] The invention relates to a formula for making concrete. Background technique [0002] Hollow square piles have three advantages over tubular piles: first, the outer cross-section is square, which is more suitable for stacking than circular, and the square cross-section of hollow square piles is more conducive to pile construction than circular. Hollow square piles will not be crushed as easily as pipe piles; second, in the same area of ​​solid shape, the circumference length is the smallest, that is, the outer circle length of the hollow square pile section is generally longer than the circumference of the pipe pile with the same cross-sectional area , which can be illustrated by simple calculations. For the pile types of friction piles and end-bearing friction piles with side friction resistance as the mainstay, hollow square piles have an advantage; third, with the same cross-sectional area, hollow square piles have a larger cross-sectional moment o...
