The fire wall 16 assembly withstood the fire endurance test without passage of flame and gases hot enough to ignite cotton waste during a four-hour fire exposure. The assembly also withstood a 45 psi water stream for five minutes immediately following the four-hour fire exposure period. This is a stringent mechanical requirement, as all fire walls 16 must maintain their integrity before, during and after a fire, per the Universal Building Code's definition of a true fire wall 16.

Lightweight cementitious foams of the invention have excellent dynamic and dimensional stability due to use of foaming system comprising polycarboxylate surfactant foam generating agent, foam stabilizer (e.g., PVOH), and shrinkage reducing admixture to inhibit plastic shrinkage and micro-cracking of cement. The foaming system can be used in conventional cement mortars or concretes as well as with exemplary cementitious slurry systems of the invention, which include an expansive agent, a cross-linking agent for the foam stabilizer. Microfibers can be used in the foam, slurry, or both, to prevent micro-cracking. Cementitious foams can be made without use of autoclave or lightweight aggregates to achieve enhanced compressive strength and thermal insulation properties that compare favorably with conventional foams and insulation materials at comparable densities.

The thickness of the sub-surface regions may be controlled by varying the viscosity and porosity of the building material substrate. The cement-polymer building material has enhanced durability, weather resistance, strength, and stiffness.

Composition for advanced hybrid geopolymeric functional materials and a process for the preparation thereof

The present invention provides a composition for advanced hybrid geopolymeric functional materials possessing very broad application spectrum ranging from cementitious materials to advanced functional materials having “Inorganic-Organic Hybrid” matrix in contrast to the limited application of conventional geopolymeric materials having “Inorganic matrix” only. The invention further relates to a process for the preparation of these materials. The process obviates the need of external addition of sodium silicate which is one of the costliest and main raw materials in conventional geopolymerisation processes. Interestingly, in the present invention the sodium silicate has been synthesized in situ by designing of conditions for synergistic and simultaneous mechano-chemical reactions among the selected raw materials viz. inorganic and organic wastes under alkaline environment. This results in the formation of “Hybrid inorganic-organic frame work” of sodium silicate, which facilitates uniform dispersion of reacting species, thus resulting in the formation of homogeneous geopolymeric matrix with improved characteristics.
