Production process of cement expanded perlite

For the production of cement perlite product bulk density expanded perlite used in 80 ~ 170kg m, Materials are Portland cement, low calcium aluminate cement, alumina cement, reference numbers 400 to 500 is /. Typical formulations of cement expanded perlite products with several different cements as binders are shown in the table below. Typical formula of cement expanded perlite products

Cement name	Expanded perlite bulk density / (km / m 3 )	Volume ratio 1	Water cement ratio	Compression ratio 2
Portland cement (labeled >400) low calcium aluminate cement alumina cement (label ≥400)	80～150 100～170 60～130	(1:10)～(1:14.5) 1: (3～10) 1: (8～10)	2.1 0.7～1.7 1.6～1.7	1.6～1.8 1.5～1.8 1.6～2.0

1 The volume ratio of the binder to the expanded perlite. 2 The ratio of the loose volume of the material used to the volume of the product. The production process is as follows:
