preparation example Construction

[0032] The invention also provides a preparation method of anti-crack and anti-seepage mortar.

[0033] Specifically, add cement, river sand, expansion agent, anti-seepage agent, and fiber to the mortar mixer and mix evenly. At the same time, add the water reducer to the mortar mixing water and mix evenly. Then add the water and water reducer mixed liquid to the mortar. In the mixer, fully stir for 1 to 3 minutes, take it out, and get a kind of anti-crack and anti-seepage mortar in coastal areas after construction.

Embodiment 1

[0037] 1. Preparation of mortar

[0038] Relying on the general contracting project of the No. 1 and No. 2 blast furnace projects of Vietnam Formosa Ha Tinh Iron and Steel Industrial Co., Ltd., the mortar mix ratio is designed mainly by selecting raw materials such as mortar cement, sand, and admixtures, and adding a certain amount to the mortar mix ratio. The anti-seepage agent, expansion agent, water reducer and a certain amount of fiber are designed for the mortar mix ratio. Because the project is located in the coastal area of ​​Chiying County, Ha Tinh Province, Vietnam, the geological survey report shows that the groundwater in the blast furnace area contains a large amount of chlorine. Ions and sulfate ions, by adding expansion agent, anti-seepage agent and anti-crack fiber, to compensate the self-shrinkage of cement mortar, improve the waterproof and anti-seepage performance of mortar, meet the requirements of high anti-crack and anti-seepage mortar for buildings in coas...

Abstract

The invention relates to an anti-crack and impervious mortar and a preparation method thereof, belonging to the technical field of building materials. The anti-crack and impervious mortar is prepared from the following components in parts by weight: 450 to 650 parts of cement, 250 to 270 parts of water, 1200 to 1500 parts of fine aggregate, 1 to 3 parts of an expansion agent, 1 to 3 parts of an impervious agent, 0.4 to 1.2 parts of fiber and 2.5 to 4.5 parts of a water reducing agent. The mortar prepared by using the method provided by the invention has the following advantages: the workability is good; the setting time of the mortar can be controlled by adjusting the usage amount of an additive; the construction time is convenient to be controlled; the construction is easy; by adding materials like anti-crack fiber, the impervious agent and the expansion agent into the mortar, anti-crack and impervious comprehensive performances of the mortar are improved; the engineering durability is effectively improved; and the preparation method for the mortar is simple and convenient to operate, and can be extensively popularized and applied.

Description

technical field [0001] The invention specifically relates to an anti-crack and anti-seepage mortar 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, coastal areas or surrounding environments contain a large amount of chloride ions and sulfate ions, which are easy to cause corrosion effects on steel bars and mortar, reduce the alkalinity of mortar, and destroy the passivation film on the surface of steel bars. , causing corrosion and expansion of steel bars, further leading to cracking and peeling of the mortar protective layer, and the continuous deterioration of the structural function and mechanical properties. At the same time, the local climate is affected by climates such as high temperature in the dry season, less rain and more wind, and humid and rainy season in the rainy season, which reduces the durability of the buildin...
