Abstract
A kind of silicate cement, it is mixed by Portland clinker, gypsum and cenosphere.It has performances such as insulation, sound insulation, proportion be little, fire-resistant, and can reduce cost, and saves the energy.
Description
The invention belongs to the technology of producing cement field, characteristics relate to the silicate cement that is mixed with cenosphere.
Existing Portland fly ash cement is to be that compound and Portland clinker and proper amount of gypsum mix grinding form with flyash.In the mix grinding process, destroyed the cenosphere in the flyash, performance such as it is little to make it lose due unit weight, and thermal conductivity is low, and introduced detrimental impurity-charcoal, and influence the performance of cement, increased production cost simultaneously.
The objective of the invention is to solve the problem of above-mentioned Portland fly ash cement, a kind of heat-insulation and heat-preservation is provided, unit weight is little, fireproof cement.
The solution of the present invention is to sneak into cenosphere to make the cement with various performances in levigated Portland clinker and gypsum.
Cenosphere utilizes sorting unit to separate from flyash.
In order to obtain the cement of different performance, the content (weight percent) of cenosphere in cement is 15-65%.
This Cement Production technology is with Wingdale, clay, iron powder mix grinding, is milled to powder together with gypsum again behind the balling-up sintering, and then mixes with cenosphere.
Advantages such as cenosphere is compared with flyash, and it is big to have specific surface area, and proportion is little, and thermal conductivity is low, and water-intake rate is low.Owing to be impregnated with complete cenosphere in this cement, so have excellent properties such as fire-resistant, insulation, sound insulation and proportion is low.
Embodiment:
1, the cenosphere cement of high index (425
#, 525
#, 625
#) consist of: cenosphere 15-35%, gypsum 5%, Portland clinker 60-80%, admixture trace.
2, consisting of of cenosphere heat preservation and soundproof energy saving cement: cenosphere 40%, Portland clinker 55%, gypsum 5%.
3, consisting of of cenosphere high temperature low-gravity oil well cement: cenosphere 50-55%, gypsum 5%, Portland clinker 40-45%
4, consisting of of cenosphere low heat cement: cenosphere 50%, slag 20%, Portland clinker 20%, gypsum 10%.
5, consisting of of cenosphere masonry cement: cenosphere 62%, gypsum 3%, Portland clinker 35%.
6, consisting of of cenosphere refractory cements: cenosphere 30-40%, gypsum 3-5%, bauxite clinker powder or chamotte powder of clay 30-40%, Portland clinker 20-30%.
Claims (3)
1, a kind of silicate cement, it contains Portland clinker and gypsum, it is characterized in that wherein also containing cenosphere.
2, a kind of as the said silicate cement of claim 1, it is characterized in that said cenosphere content (weight percent) is 15-65%.
3, a kind of method that is used to produce as claim 1 or 2 said silicate cements will be milled to powder with gypsum behind Wingdale, clay, iron powder mix grinding, the balling-up sintering more together, it is characterized in that levigated powder and cenosphere are mixed.
