Abstract:
1. A method of forming a composite construction material comprising the steps of: providing a mixture of at least one of a pozzolanic material and 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; 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; 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; and combining a mixture of the alumino-silicate cementitious material and water with at least one of a coarse aggregate, a fine aggregate and a plasticizer to form a composite construction material, wherein the composite construction material is concrete, wherein the method of forming the composite construction material is free of carbon dioxide emission associated with the formation of the composite construction material; wherein a weight of the mixture of the pozzolanic material and the kaolin clay that is used to form the alumino-silicate cementitious material ranges between 350 kilograms and 400 kilograms; wherein the weight of a sodium hydroxide that is used to form the alumino-silicate cementitious material ranges between 30 kilograms and 60 kilograms; wherein the weight of the sodium silicate that is used to form the alumino-silicate cementitious material ranges between 100 kilograms and 150 kilograms; wherein the weight of the fine aggregate used to form the concrete ranges between 500 kilograms and 600 kilograms; wherein the weight of the coarse aggregate used to form the concrete ranges between 1200 kilograms and 1400 kilograms; and wherein the weight of the water used to form the concrete ranges between 60 kilograms and 400 kilograms.
