Cement blanket manufacturer

Hanji cement blanket is a kind of concrete canvas, which combines textile and cement together. The magic of this kind of cement blanket is that it can be used quickly and quickly, and it is suitable for the fast rhythm of modern people.

Nowadays, the invention of new cement blanket material appears, which can serve us all well.

The size of cement blanket can be determined according to the size of construction site

Before watering, it has the softness and toughness of textiles. After watering, it has the hardness and strength of concrete, which is very magical! It can be called the most convenient concrete in history. It's easy to roll up and store like cloth! It's only 15 kilos per square meter, so it's very convenient to transport. What size you want can be cut by yourself! Cut at will, usually the new cement blanket looks like an ordinary blanket, but after pouring water, the new cement blanket will quickly become a hard concrete layer. Good toughness, so that it can not only hang vertically, but also lay in the groove

2. Cement blanket can be widely used in railway, highway, water conservancy, agricultural irrigation and other fields. Cement blanket can not only save 90% material, but also shorten 60% construction period. The cement blanket has been valued at over 100 million yuan. Even in the United States, it is being purchased in large quantities and widely used. With the existence of fiber skeleton and the uniformity of concrete powder, this material will not crack after solidification and has a long service life. Cement blanket like cloth storage, transportation, laying up is also very convenient. The advantage of 2 cement blanket is that the construction is convenient, but the disadvantage is that the bending strength is low and the construction requirements are strict. Concrete canvas usually looks like an ordinary blanket.

Cement blanket manufacturers can use salt water or non salt water to realize hydration reaction. The minimum weight ratio of water to cement blanket is 1 ∶ 2. Excessive hydration of cement blanket will not occur, so it is always recommended to use excessive water. Water can be sprayed several times on the fiber surface until the cement blanket is saturated. Because the cement blanket absorbs moisture, it darkens first and then becomes lighter. When water accumulates or flows down the surface, the cement blanket is saturated with water. After the initial hydration reaction, the cement blanket shall be re wetted at least once between one and two hours. This is especially necessary in high temperature and dry weather, as evaporation of water can cause excessive drying of concrete.

The product hj008 cement blanket is the most prone to excessive drying. No matter what the weather is, one to two hours after hydration reaction, it should be rewatered once or several times. Do not use high-pressure water spray gun to spray water directly on the cement blanket, otherwise the surface of cement blanket will be washed into groove shape. If the cement blanket is not fully protected by water, the setting will be delayed and the material strength will be improved

It will go down. If the setting time is delayed, it should be rewatered with a large amount of water. Cement blanket can be used under water. At this time, because it is immersed in water, hydration reaction can take place fully.
