摘要： A method of preparing a concrete composition includes utilizing a controller to control a process including circulating process water in a process water supply loop for a predetermined period while monitoring and controlling the temperature and flow rate of the process water, circulating aqueous-based air entrainment solution in an aqueous-based air entrainment solution supply loop for the predetermined period and controlling the flow rate of the aqueous-based air entrainment solution and after the predetermined period of time in which the flow of process water and aqueous-based air entrainment solution have stabilized, simultaneously actuating valves to divert and mix the process water, the aqueous-based air entrainment solution and compressed air to produce an air-entrained foam and mixing the foam with a concrete composition.

摘要： A process and apparatus for producing a low density foam concrete, in which a recycled, excavated material is used to form the concrete mix. The material may be crushed and graded and used in a ratio of 6:1 with the cement component. A preformed foam may be used to obtain a high void volume and a placticiser added to improve fluidity. The foam concrete is manufactured on-site on a continuous basis using a mobile concrete making vehicle (1) having an elongate tubular mixer (4) into which the components are introduced at selected points (20A,20B,20C) along its length, so as to control the final composition of the mix. The mixer (4) has internal agitating means (22) that cause backflow to enable the concrete to be dispensed directly at ground level.

摘要： A foam injection system for use in the manufacture of cementitious products includes a foam injection body and first and second port inserts. The foam injection body defines a slurry passageway and a port passageway having a port opening in fluid communication with the slurry passageway. The first and second port inserts respectively define first and second foam passageways having first and second orifice sizes. The first and second orifice sizes are different. The first and second port inserts are adapted to removably mount to the foam injection body such that the respective foam passageway is in fluid communication with the slurry passageway via the port opening of the port passageway. One port insert can be replaced with another to readily vary the pressure of the foam passing through the particular port insert and injected into a cementitious slurry traveling through the slurry passageway.

摘要： Foam is generated by introducing (14) a mixture of gas and a liquid into a vessel (12) to pass through a passage (30) in the vessel. The flow of the mixture through the passage is increased to increase the velocity of the mixture and cause corresponding shearing forces on the mixture to create a turbulence and form foam from the mixture. A restrictor (22) can be moved in the passage to vary the amount of restriction and, therefore, the amount of the foam.

摘要： The present invention provides for an acoustically absorbent porous panel that is both rigid and resistant to sagging caused by moisture. The acoustically absorbent porous panel is comprised of at least two layers. The first layer is a facing layer formed from a cured aqueous foamed cementitious material. The foamed cementitious material comprises on a wet basis about 53% to about 68% by weight cement, about 17% to about 48% by weight water, about 0.05% to about 5% by weight fiber, and about 0.01% to about 10% by weight surfactant. Additionally, pores distributed within the cured material comprising about 75% to about 95% by volume of the material. The second layer is a backing layer that is affixed to the facing layer.

摘要： The invention relates to a method for producing foaming materials with an inorganic base, especially a phosphate base. Said materials consist of at least two aqueous, essentially inorganic constituents A and B. The aim of the invention is to provide a means of conveying and exactly mixing two or more constituents to a large extent continuously, said constituents reacting to form a solid material, especially a light material. To this end, the two components A and B are each fed to different vessels (9) or are produced in said vessels and continuously conveyed through lines to a mixing device (6) where they are mixed within a period of a few seconds. The mixed material is discharged within a few seconds, whereupon the two components A and B react with each other.
