A new and innovative fireproof coating is provided. The fireproof coating exhibits high heat insulation combined with a low flame spread and low smoke density. The fireproof coating can be applied to any suitable structure for which fireproofing is beneficial. An advantage of the fireproof coating is low weight and high flexibility compared to conventional fireproofing technologies while still providing equivalent or better fireproofing properties. The provided fireproof coating has a low thermal conductivity and high emissivity, each of which provide the coating with desirable fireproofing properties. The fireproof coating also demonstrates its advantageous fireproofing properties over a wide range of temperatures and adds minimal thickness to the structures on which it is applied while still providing equivalent or better fireproofing properties as other, thicker fireproof materials.

The invention relates to processes for making improved ultra-high performance microfiber concrete and articles made from the same. The invention includes blending first dry constituents of fine aggregate, steel fiber, and cement to yield a first homogenous dry mix, optionally adding carbon nanotubes and/or silicon carbide microinclusions, followed by blending with second dry constituents of silica fume, silica flour, and cenospheres to obtain a second homogenous dry mix, followed by adding water only, with further blending, and finally adding a superplasticizer admix and a water-reducing admix to obtain ultra high performance microfiber concrete. The invention also relates to voltage heating for curing and for creating heated UHPC articles.

A cementitious composite and cured masonry block made from the cementitious composite. The cementitious composite contains a cement, a non-rubber aggregate, a crumb rubber and at least one of cement kiln dust and limestone powder. The crumb rubber aggregate is extracted from scrap tires after being processed and then mixed in specified percentages with the aggregate, the cement and water, then cured in forms to make the masonry blocks. In the present disclosure sand, which is used in conventional masonry blocks, is at least partially replaced with crumb rubber to produce a sand-free or sand-reduced masonry block that contains crumb rubber. The crumb rubber masonry blocks satisfy the ASTM non-load bearing requirements. The use of crumb rubber decreases the unit weight and increases thermal resistance of the masonry blocks. The use of cement kiln dust or limestone as a partial replacement of cement will lead to decrease in the cost. The use of industrial waste materials, such as crumb rubber, limestone powder and cement kiln dust, will lead to economic and environmental benefits.

The present disclosure provides methods of making organosiloxane polymer compositions from hydrosilylation curable compositions comprising at least the components (a) and (b) and at least one of components (c) and (d): (a) an organosiloxane resin material comprising aliphatic unsaturation; and (b) an organosiloxane crosslinker comprising multiple silicon atom-bonded hydrogen atoms (e.g., an SiH siloxane); in combination with at least one of (c) at least one organosiloxane comprising at least two silicon atom-bonded hydrogen atoms; and (d) at least one organosiloxane comprising at least two silicon atom-bonded hydrocarbyl groups comprising aliphatic unsaturation (e.g., a di-vinyl functional siloxane). Such hydrosilylation curable compositions have, in some instances, significantly faster cure speed, relative to their condensation curable counterparts. A faster cure speed can be important for encapsulating electronic devices, such as light-emitting diode (LED) chip devices, including devices having tall structures.
