The methods include the steps of forming a mixture of raw material containing CaO, MgO, Al2O3, Fe2O3, TiO2, Mn2O3, SiO2, SO3, Na2O, K2O, P2O5 and F, respectively designated C, M, A, F, T, Mn, S, {overscore (S)}, N, K, P and f, and heating said mixture to an elevated temperature between 900° C. and 1,200° C.; before determining average amount of crystals X, Y, and Z. Final mixtures comprising these clinkers and hydraulic or portland type cement are made to produce cement compositions having crystal X concentrations of approximately 5% to 35% by weight, crystal Y concentrations of approximately 5% to 40% by weight, and / or crystal Z concentrations of approximately 5% to 40% by weight, with the remainder being hydraulic or portland type cement. The cements so produced are rapid hardening and exhibit high strengths ranging from 2,000 psi to 7,000 psi in one hour, 6,000 to 8,000 psi in one day and 9,000 to 12,000 psi in 28 days. They are sulfate and sea-water attack resistant and have low heats of hydration, minimal shrinkage, and high water impermeability. The methods claimed also results in significant reduction in gaseous emissions including SOx, NOx and COx.

A landfill cover composition comprising a concentrate formulated to include a hardening agent, a thickener and emulsifier, and a super absorbent polymer, mixable with water and a filler material, such as cellulose or wood fiber mulch. A mixture of water, filler material and concentrate is sprayed on the surface of a landfill refuse layer and hardened to provide at least a temporary cover as an alternative to a significantly thicker or deeper layer of conventional soil or earth cover. The biodegradable composition preferably includes Plaster of Paris and guar gum compositions and cross-linked sodium acrylate polymer fines, mixed with the filler material and water at a landfill site for reducing transportation and handling costs.

The invention provides after-sun repair serum containing dendrobium candidum.

A pressure vessel at least includes a main vessel, an air entry valve, a water entry valve, a drain valve and a control valve. The drain valve is provided with a valve base set on the top of the main vessel, a piston unit inserted inside the valve base able to be moved upwards and a spring installed between the piston member and the valve base. In addition, the pressured water in the main vessel coming from the water entry valve and the air entry valve can be stored in the control valve and guided to a chamber between the piston unit and the valve base, enabling the piston member to surpasses the elasticity and the water pressure to move up to separate from a drain exit of the main vessel for flushing a toilet. Therefore, the present invention has a simple structure, easy to assemble, preventing accidental flushing.
