摘要： An additive for use in the preparation of lightweight concrete, said additive including a blend of from around 40% to 99% of organic polymeric material and from 1% to around 60% clean air entraining agent. The additive is particularly suitable for the preparation of lightweight concrete which uses polystyrene aggregate. It provides for excellent dispersion of the polystyrene aggregate and improved bond between the polystyrene aggregate and surrounding cementitious binder. The resultant lightweight concrete formulation may be pumped and is particularly suitable for sandwich wall construction.

摘要： A formulation for preparing a cementitious product comprising a cementitious material, a siliceous material, and a low bulk density material being substantially calcium silicate hydrate and including unreacted siliceous reactant. A method of forming a cementitious product comprises adding a cementitious material, a siliceous material and a low bulk density material to water to form a slurry, forming a green shaped article from the slurry and curing the article in an autoclave, wherein the low bulk density material is substantially calcium silicate hydrate and includes unreacted siliceous reactant.

摘要： The present invention relates to methods for detection and evaluation of metabolic activity of eukaryotic and/or prokaryotic cells based upon their ability to consume dissolved oxygen. The methods utilize a luminescence detection system which makes use of the sensitivity of the luminescent emission of certain compounds to the presence of oxygen, which quenches (diminishes) the compound's luminescent emission in a concentration dependent manner. Respiring eukaryotic and/or prokaryotic cells will affect the oxygen concentration of a liquid medium in which they are immersed. Thus, this invention provides a convenient system to gather information on the presence, identification, quantification and cytotoxic activity of eukaryotic and/or prokaryotic cells by determining their effect on the oxygen concentration of the media in which they are present.
