Q:GRC composite column, which is better?

This is the performance of the GRC minimum guarantee project, not buried steel or cold wire drawing with pre inside, a few years will rust off, because the GRC thin wall, the protective layer is not enough, you should understand the serious consequences, you should also want to get it, the embedded metal should not be called GRC, GRC glass fiber reinforced cement component referred to, the use of metal is a short-term enhancement.

Q:What is a GRC pile composite foundation?

CFG pile is English Cement Fly-ash Gravel acronym, meaning cement fly ash gravel pile, composed of gravel, stone, sand, fly ash cement mixed with water, the variable strength pile with certain strength made pile with various machinery. CFG pile is a kind of low strength concrete pile. It can make full use of the bearing capacity of the soil between the piles, and transfer the load to the deep foundation. It has better technical performance and economic effect.

Q:GRC light partition board installation scheme for construction of hydropower pipelines

In the installation of water tanks, magnetic pots, electrical switches, sockets, wall lamps and other water appliances, according to the requirements of the size of the chisel hole (not tick), can not use heavy hammer, so as not to shock the wall panels. After the pipeline is buried, immediately cement mortar, putty, plug and scrape. For larger, heavier weight apparatus such as the power box is to cut holes according to size requirements (not, then drove) wedge or steel embedded parts with cement mortar pouring plug, after the installation of 7d.

Q:What is the best type of cement used in plain GRC components? What's the best filler? How dose glass fiber be controlled?

Cement: Cement usually used in GRC, mainly consisting of fast hard sulphoaluminate cement, low alkalinity sulphoaluminate cement, ordinary portland cement, and white Portland cement.Fiber: fibers used in GRC materials must be alkali resistant glass fibers, including alkali resistant fiberglass, roving, alkali resistant fiberglass, short cut, alkali resistant fiberglass mesh. Europe and the United States require GRC in the use of glass fiber zirconia content of not less than 16.5%, China requires the use of ordinary portland cement, zirconia content of not less than 16.5%.

Q:How to identify new wall panels

In accordance with the different materials of new wall panels can be divided into three types: (1) GRC new wall, the main material is decreasing sulfur aluminum acid salt cement, coal ash, ceramsite, perlite, mesh or steel mesh; (2) kneading cement wall, the main material is ordinary cement, coal ash, washed; (3) high strength cement wall, the main material is magnesium chloride and Magnesium Oxide, commonly known as magnesite, alkali mesh.

Q:What's the difference between partitions?

There are many types of partition board, such as partition board raw material is not the same, the product is not the same, such as composite fiber, cement, foam, ceramsite and so on.There are many types of partition board products, such as interior wall panels, exterior wall panels, their length, thickness requirements are not the same.

Q:What is the standard value of GRC durability?

Truly qualified GRC products and its durability is almost the same concrete (generally 50 years), but the domestic nine out of ten GRC are only a few years of life, especially inside the reinforced GRC, think of the strength of the mortar is much clear that the quality of life and what is the fake GRC. Only the alkali resistant fiber (of which two zirconia content is an important index to more than 16%) the content of not less than 4.5% is qualified, and its production process and standard, to dense.

Q:GRC cement products have cracks, what are the reasons?

Strengthening the maintenance, reducing the hydration heat of cement and controlling the internal temperature of concrete products are effective measures to reduce the cracks on the surface of cement products.

Q:What is the working principle of the mortar pump?

7, the piston 8 reversing valve at the same time, S 10 also reversing, the movable end and conveying cylinder 6 is 6 cylinder in the mortar conveying push 8 piston, enter S tube valve 10 is pressed into the discharge port 14; at the same time in the piston 7, conveying cylinder 5 inhalation of mortar, sent in preparation for the next step pressure. Thus, the mortar is pressed from the hopper to the conveying pipe, and this process is called pumping".
