How to apply the quota of cement and vermiculite insulation layer?
Vermiculite is a kind of hydrate, which is blocky, flaky and granular. It is the product of weathering and alteration of natural mineral such as biotite. The interlayer water molecule is ignited at high temperature, and the volume is increased by 18-25 times. Rich in nitrogen, phosphorus, potassium, aluminum, iron, magnesium, silicate and other ingredients. Vermiculite has higher layer charge number, so it has higher cation exchange capacity and stronger cation exchange adsorption capacity. Characteristics: light weight, and good adsorption properties, not decay, can be used for 3-5 years (unlike the humus, coconut shell, clothing and other perishable).
The present price is the separation of quantity and price.Here, the amount consumed. The consumption of fixed consumption is only the price of a natural machine. The corresponding "04 consumption quota" in Guizhou."Consumption corresponding to the so-called price is fixed base price, respectively, corresponding to the combination of talent prices. The corresponding books, such as "Guizhou city 08 price list", because different regions of the price list is not the sameFor example, we want to build a brick wall now 1.3 cubic meters of water mixing, Lane corresponding to the fixed quota items such as 3-1, the consumer can find the corresponding item is brick mixing.
Cement and expanded vermiculite, cement should be no less than 325, usually choose 425 ordinary Portland cement. The volume ratio of cement and expanded vermiculite is generally 1:5, which is economical and reasonable. Cement and sand aspect than the general 1:1. Site inspection method: mix the cement paste with fine powder and knead it by hand.
