Biomaterials, in particular bone foams, a process for preparing such materials as well as an applicator for applying the biomaterials directly to the patient's application site, and the use of a composition comprising water, a surfactant and a propellant in the preparation of a bone foam for the preparation of a calcium phosphate foam wherein the foam is obtainable by the mixture of at least two phases, a first phase comprising water and optionally a propellant, a second phase comprising one or more sources for calcium and/or phosphate, and wherein the foaming is performed during the mixture of the at least two phases to provide an improved calcium phosphate foam, process for the preparation of a calcium phosphate foam, use of a composition, solid state structure, calcium phosphate cement foam and bone foam applicator.

Provided herein is a joint compound having a composition to allow tools to easily clean up, comprising water, at least one inert filler, and a binder comprising a sulfonated starch, and a method of preparing the joint compound.

The present invention discloses a high-flow lightweight insulating concrete and preparation method thereof. The high-flow lightweight insulating concrete includes cement, water, admixture and environmental friendly additives, wherein the mass ratio of the cement, admixture, environmental friendly additive and water is (15-25):(60-75):(0.5-1.5):(8-12). The present invention provides a high-flow lightweight insulating concrete and preparation method thereof, using effective gel in the construction debris as raw material. The renewable environmentally friendly active materials are prepared from the construction debris and have the characteristic of high-flow, which are suitable for the cast-in-place construction of the non-load-bearing wall. The construction process has advantages of simple, reliable, lightweight, high strength and cost-effective. And the non-load-bearing wall has the advantages of sound insulation, thermal insulation, is environmental friendly and durable.

A mixture for covering joints between building boards in drywall constructions, which can be applied by spraying, wherein the mixture contains 0.01 to 10 wt.-% of a fibrous material, 1 to 20 wt.-% of a binder, 1 to 10 wt.-% of a thickener and 50 to 97.99 wt.-% of a solvent, and in which the fibrous material and the binder are present in a predetermined ratio in the range from 1:1 to 1:5. The present invention also relates to a method for filling joints in drywall constructions using such mixture, drywall constructions produced accordingly and the use of the sprayable mixtures described for reinforcing a drywall construction in the contact area between construction panels.

It discloses cement grinding aids prepared with waste antifreeze which comprises the following components in parts by weight: 20-75 parts of pretreated waste antifreeze, 5-40 parts of alkanolamine, 1-5 parts of acid solution, 3-12 parts of saccharide and 15-50 parts of water. The pretreated waste antifreeze is prepared by adding an alkaline solution into waste antifreeze to regulate the pH value, adding a flocculant, and stirring and standing; separating upper-layer oil, and then filtering to remove flocculent precipitates, thus obtaining a clear mixed solution.
