Abstract

The invention relates to the field of concrete, and particularly discloses mass concrete as well as a preparation method and application thereof. The mass concrete is prepared from the following raw materials in parts by weight: 340-355 parts of cement; 40 to 45 parts of fly ash; 100 to 110 parts of mineral powder; 680 to 720 parts of fine aggregate; 1080 to 1100 parts of coarse aggregate; 7-9 parts of a water reducing agent; and 135 to 145 parts of water. The preparation method comprises the following steps: weighing the cement, the fly ash, the mineral powder, the fine aggregate and the coarse aggregate in proportion, and uniformly mixing and stirring to obtain a first mixture; and weighing the water reducing agent and the water according to the proportion, adding the weighed water reducing agent into the water, uniformly mixing, adding the water doped with the water reducing agent into the first mixture, and uniformly stirring to obtain the mass concrete. The mass concrete has the advantages that the crack generation probability is reduced, and the crack generation amount is reduced.

Description

technical field

[0001] The present application relates to the field of concrete, and more specifically, it relates to a mass concrete and a preparation method thereof. Background technique

[0002] In the construction process of hydraulic structures such as bridges, it is first necessary to carry out the supporting layout and construction of the pile foundation, that is, the cap, and such caps often have a large structural size, especially for the main cable tower foundation cap, which not only has a large structural size, but also Moreover, the requirements for the strength grade of the cap concrete are also relatively high. However, for mass concrete, due to the high heat of hydration, the temperature difference between the inside and outside of the concrete is large, and cracks are easily generated. These cracks will reduce the original bearing capacity of the engineering structure and seriously affect the durability of the structure.

[0003] At the same time, since bri...
