Abstract: The present invention relates to epoxy curing agents which are obtained from the reaction of a polyalkylene polyether modified polyepoxide resin and a polyamine component. They polyamine component is a reaction product of a polyethylene polyamine having 3 to 10 nitrogen atoms, for example, diethylenetriamine (DETA), and at least one aldehyde having 1 to 8 carbon atoms, for example, formaldehyde. The epoxy curing agent may be used as part of a two component coating system in the curing of liquid or pre-dispersed curable epoxy resins.

Abstract: A concrete product is produced by providing red dune sand having a particle size of 45 microns or less and mixing the red dune sand with hydraulic cement in a ratio of about 30% of the cement being replaced by the red dune sand. The cement and red dune sand are then mixed with fine and course aggregate, water and a superplasticizer and cast after pouring into a mold cavity. Then within 24 hours of casting, the cast article is steam cured for 12 hours under atmospheric pressure, demolded and placed in an auto clave at 100% humidity. The temperature in the auto clave is raised to 180° C. within one to two hours and maintained at that temperature for 4 to 5 hours. The temperature also increases the pressure to about 10 bars. The pressure is released to reach atmospheric pressure within 20-30 minutes and the temperature reduced gradually, so that the article can be removed.

Abstract: A concrete comprises in relative parts by weight: 100 of Portland cement; 0.25 to 9 of a defoamer; 0.001 to 6 of a surfactant; 0 to 230 of coarse gravel and/or fine gravel and/or shear enhancers; 0 to 85 of sand; 0 to 60 of a particulate pozzolanic or non-pozzolanic material or a mixture thereof having a mean particle size less than 15 micrometers; 0 to 80 of a particulate pozzolanic or non-pozzolanic material or a mixture thereof having a mean particle size between 15 to 88 micrometers; 0.3 to 18 of a water-reducing superplasticizer; 0 to 14 of polyethylene fibers; and 5 to 40 of water. An air mixing process using a tightly sealed mixing tool is used to thoroughly mix the constituents of the concrete before adding the water for curing. By adjusting relative parts in the composition, concretes of high and ultrahigh performance can be achieved efficiently.

Abstract: A formulation for obtaining a translucent concrete mixture comprising a mixture of polycarbonate and epoxy matrices, as well as glass fibres, optical fibres, colloidal silica, silica and Portland cement. The invention has greater mechanical strength properties than those of a standard concrete, with lower density and mechanical characteristics that enable same to be used in both a structural and architectonic manner. The formulation used to obtain the translucent concrete mixture comprises a type of concrete that is different from those currently available, which combines the advantages of existing concretes with translucency.
