Embodiment 1

[0035] Relying on the general contracting project of the No. 1 and No. 2 blast furnace projects of Vietnam Formosa Plastics Ha Tinh Iron and Steel Industrial Co., Ltd., the foundation of the Vietnam Formosa Plastics blast furnace was prepared. The foundation platform of the Formosa Plastics blast furnace was designed to be 43.8 meters long and 30.8 meters wide. The elevation is FL-4.100m, the design label of the concrete platform is C40, and the theoretical total is 5396m 3 , the amount of concrete poured at one time is 5300m 3 , the design strength level requirement is C40.

[0036] By selecting raw materials such as concrete cement, sand, stone, and admixtures in Vietnam, the concrete mix ratio design is carried out, mainly by adding a certain amount of rust inhibitor and furnace stone powder to the concrete mix ratio, because there are no mineral admixtures in Vietnam, the main The anti-crack performance of concrete is considered from the two aspects of reducing the heat o...

Abstract

The invention relates to anticrack anticorrosion mass concrete and a preparation method thereof and belongs to the technical field of building materials. The invention provides the anti-crack anticorrosion mass concrete. The anticrack anticorrosion mass concrete is prepared from 1 part by weight of cement, 0.25-0.41 parts by weight of hearthstone powder, 0.50-0.65 parts by weight of water, 3.21-3.85 parts by weight of coarse aggregate, 2.51-3.5 parts by weight of fine aggregate, 0.015-0.032 parts by weight of a corrosion inhibitor, 0.005-0.012 parts by weight of a water reducer and 0.001-0.006 parts by weight of polypropylene fibers. The blast furnace base anticrack anticorrosion mass concrete, which is prepared from specific components and satisfies saline-alkali geological environment requirements, has good workability and high strength, is convenient for construction work control and concrete construction, has a simple formula, greatly saves a cost, is prepared through simple and easy processes, is free of mineral admixtures and can be promoted in saline-alkali geological environments in Vietnam and China.

Description

technical field [0001] The invention relates to anti-crack and anti-corrosion mass concrete and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] For marine buildings, sea sand buildings and buildings in saline-alkali areas, the saline-alkali area or the surrounding environment contains a large amount of chloride ions and sulfate ions, which are easy to cause corrosion effects on steel bars and concrete, reduce the alkalinity of concrete, and destroy the passivation film on the surface of steel bars , causing corrosion and expansion of steel bars, further leading to cracking and spalling of the concrete protective layer, and the continuous deterioration of the structural function and mechanical properties. For this reason, experts at home and abroad have proposed various measures to improve the anti-corrosion ability of concrete structures, among which adding anti-corrosion agents to concrete is an effective m...
