摘要:
Disclosed are a system, a method and/or composition of reduction of carbon dioxide in the manufacturing of cement and concrete. In one embodiment, a method of producing a concrete, includes preparing a dried powder mixture of an alkali hydroxide, a sodium silicate, clay and a pozzolanic material. The dried powder with water may be reacted to form a cement paste. In addition, the cement paste may be mixed with at one of sand, an aggregate, a plasticizer and a nano additive to form the concrete.

Disclosed are a system, a method and/or composition of environment friendly composite construction material. In one aspect, a method includes providing a mixture of a pozzolanic material and/or a kaolin clay with an activator solution to form an alumino-silicate cementitious material through a resulting geo-polymerization process. The alumino-silicate cementitious material is in the form of a paste. The method also includes processing the alumino-silicate cementitious material to transform the alumino-silicate cementitious material that is in the form of the paste to a form of a powder of the alumino-silicate cementitious material. The method further includes mixing the alumino-silicate cementitious material which is in the form of the powder with water to control a workability of the alumino-silicate cementitious material. Furthermore the method includes combining a mixture of the alumino-silicate cementitious material and water with a coarse aggregate, a fine aggregate and/or a plasticizer to form a composite construction material.
摘要:
A method of coating a geopolymer onto an article that is made of high heat applicable material, the method comprising the steps of providing geopolymer paste prepared from reacting fly ash-derived pozzolanic material with an alkaline activator solution; coating the geopolymer paste onto the article; curing the coated article; and sintering the cured article at a temperature ranging from 100° C. to 1500° C.
