Disclosed are a lightweight conductive mortar material, a preparation method therefor and use thereof. The lightweight conductive mortar material includes the following components in parts by weight: 100 parts of cement, 25 parts to 60 parts of a conductive porous lightweight aggregate loaded with a modified agar gel, and 30 parts to 45 parts of water.

The invention relates to a method for producing thermal energy storage components comprising phase change material embedded into porous components, in particular for use in cement-based compositions. The method comprises: an impregnation step (10) comprising introducing phase change material into porous components inside a main vessel (102) by vacuum impregnation; an injection step (12) at a temperature within a melting temperature range of said phase change material and under an overpressure, in order vacuuming to force the phase change material into the porous components; and an entrapment step (14) comprising reducing the temperature inside the main vessel, while maintaining an the overpressure, in order to lower the viscosity of said phase change material.

It has been unexpectedly discovered that the addition of a natural or other pozzolan to non-spec fly ash significantly improves the properties of the non-spec fly ash to the extent it can be certified under ASTM C618 and AASHTO 295, as either a Class F or Class C fly ash. The natural pozzolan may be a volcanic ejecta, such as pumice or perlite. Other pozzolans may also be used for this beneficiation process. Many pozzolans are experimentally tested and may be used to beneficiate non-spec fly ash into certifiable Class F fly ash. Additionally, this disclosure provides a method of converting a Class C fly ash to a more valuable Class F fly ash. This discovery will extend diminishing Class F fly ash supplies and turn non-spec fly ash waste streams into valuable, certified fly ash pozzolan which will protect and enhance concrete, mortars and grouts.

The present disclosure relates to the building industry and in particular to a block for use in automated building construction. In one aspect, the block comprises a generally cuboid body having a top and a base, a length extending between a pair of opposed ends, and a width extending between a pair of opposed sides; the body including a plurality of hollow cores extending from said top to said base, and arranged in a row between said opposed ends; wherein each core has a rectilinear cross-sectional shape; and wherein the thickness of the block between each pair of adjacent cores is at least double the thickness of the block on all other sides of each core, so that the block is divisible into a plurality of substantially identical block portions, each portion including four walls of substantially uniform wall thickness about its core.

Described herein is a method for preparing decorative concrete top ping which overcomes the limitations associated with epoxy Terrazzo floors. Specifically, the decorative concrete topping mixture described herein has a low crack potential, high strength and durability, much longer working time, thereby allowing for the material to be mixed in larger quantities and simplifying application. A binder composition made of Portland cement and pozzolanic materials is mixed with an decorative aggregate and other additives before pumping the concrete topping mixture onto a subfloor and allowing the concrete topping mixture to cure.
