Disclosed is a concrete product incorporating rubber aggregate produced by casting under pressure. The concrete product may optionally be cast at 6.9-27.7 MPa for periods of, for example, 24 hours. In one embodiment the rubber aggregate may comprise coarse and/or fine rubber aggregate to replace natural sources of coarse and fine aggregate. Casting under pressure was found to generally improve the performance characteristics of the concrete when compared to corresponding concrete cast without pressure.

A colored cementitious composition is provided that is composed of hydraulic cement and a liquid coloring suspension. The liquid coloring suspension for cementitious compositions contains polycarboxylate dispersant, pigment, and a polysaccharide thixotropic additive. The liquid coloring suspension has improved viscosity consistency, improved shelf-life, anti-settling and anti-sludging properties, and decreased polycarboxylate dispersant requirements.

A method is provided for preserving cooking oil in a food fryer which comprises contacting the oil in situ with at least one oil-permeable cement body which is a stand-alone block and which has been hydraulically hardened from a paste comprising (i) white OPC clinker, (ii) white OPC or (iii) a mixture of white OPC clinker and white OPC, wherein the porosity of the cement body, estimable from the difference between its water-saturated and dry weights, is 30-55%, pores in the body being oil receptive by virtue of low un-bound water content.
