Waterproof concrete and production process thereof

Abstract

The invention discloses waterproof concrete and production process thereof, and relates to the field of concrete. The problem of poor waterproofing effect of concrete in the prior art is solved. The concrete comprises the following components of 10 wt%-30 wt% of cement, 20 wt%-30 wt% of fine aggregate sand, 20 wt%-30 wt% of coarse aggregate sand, 10 wt%-20 wt% of water and waterproofing material,wherein the waterproofing material comprises 0.8 wt%-1.2 wt% of graphene, 5 wt%-15 wt% of PVA, 0.5 wt%-1.5 wt% of sodium chloride and 2 wt%-7 wt% of ascorbic acid. The concrete has the advantages of capable of improving the waterproofing performance of concrete and simple in production process.

Description

technical field [0001] The invention relates to the field of concrete, in particular to a waterproof concrete and a production process thereof. Background technique [0002] Concrete is one of the most important contemporary civil engineering materials. It is prepared in a certain proportion by cementitious materials, granular aggregates (also known as aggregates), water and, if necessary, admixtures and admixtures. It is a kind of artificial stone made by stirring, compacting and curing. Concrete has the characteristics of abundant raw materials, low price, and simple production process, so its consumption is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. [0003] However, the concrete in the prior art does not have a particularly good waterproof effect. Such phenomena are often encountered in daily life, such as water seepage and water leakage from the roof, water seep...

AI Technical Summary

Problems solved by technology

[0003] However, the concrete in the prior art does not have a particularly good waterproof effect. Such phenomena are often encountered in daily life, such as water seepage and water leakage from the roof, water seepage from the windows, and water seepage from the balcony wall. It belongs to one's own home, and it is often not handled well, and it will also affect the relationship between neighbors

Moreover, when water enters the main structure of the building, it is easy to cause harm to the cement, steel bars and wood in the reinforced concrete, which greatly reduces the service life of the building.

[0004] The existing waterproof materials on the market include: A. Polyurethane: oil-based materials, which have the best performance in the current waterproof coatings, but the environmental performance is relatively poor and the smell is very smelly; B. Acrylic: water-based materials, which have better performance. But the price is expensive, and it is not suitable for the humid weather in the south; C, JS polymers: water-based materials, adding cement and other inorganic materials in use, can be bonded to the cement base surface, but its waterproof effect is not ideal; D, Mortar: water-based material, which can be bonded to the cement base, but its service life is short, and it will take time, effort and money to replace it

The above four types have their own advantages and disadvantages, but the common disadvantages are that they are not environmentally friendly, have a strong smell, and are all coatings, which cannot solve the waterproof problem from the performance of concrete itself.
