Patent Number Title Of Patent Date Issued
5110084 Form device for cellular concrete and method of making such concrete May 5, 1992
A form device for cellular concrete, including a number of piled-up form units having a heat-insulating bottom and shell, a heat-insulating top board, and a bottom-to-shell joint. A cellular concrete manufacture is produced by mixing cement with warm water at a temperature of 40.degree.
5091014 Strengthened cellular concrete compositions and method of making February 25, 1992
A cellular concrete composition containing as a frother, polycarboxylic acids and organosilicon compounds, or together with alkylene glycols and/or nonionic active agents. It is made by mixing a cement paste with a bubbled frother solution containing polycarboxylic acids and organosilico
5087287 Strengthened cellular concrete compositions and method of making February 11, 1992
A cellular concrete composition having improved strength consisting of hydraulic cement, water and at least one alpha, beta-unsaturated dicarboxylic acid such a maleic or fumaric acid. A method is also provided comprising preparing a cement paste containing hyraulic cement and water,
5047085 Method of making strengthened cellular concrete compositions containing alpha,beta-unsaturated d September 10, 1991
A cellular concrete composition containing as a frother polycarboxylic acids or together with alkylene glycols and/or nonionic surface active agents. It is made by mixing a cement paste with a bubbled frother solution containing polycarboxylic acids or together with alkylene glycols
