Abstract: The present invention discloses an optimized preparation method of a carbonization-based lightweight CO2 foamed cement-based material, and belongs to the field of geotechnical engineering materials. The preparation method includes: step S1: pre-screening existing common cement-based foaming agents and foam stabilizers; step S2: preparing a water-based carbon dioxide foam; step S3: preparing a cement slurry, and mixing the water-based carbon dioxide foam with the cement slurry to prepare a lightweight CO2 foamed cement-based material; step S4: selecting foaming agents of different types and different concentrations and foam stabilizers of different types and different concentrations to prepare slurries, subjecting the slurries to slurry performance tests, and selecting the optimal ones; step S5: optimizing initial water-to-cement ratio and foam-to-slurry ratio parameters; and step S6: optimizing a gas-filling volume parameter (water pump speed).

Abstract: The disclosure discloses an ultra-dry three-phase flue gas foam for oil-gas fields and preparation method thereof. The ultra-dry three-phase flue gas foam is produced by a gas phase, a liquid phase and a solid phase; the gas phase is a flue gas; the foaming solution is an aqueous solution of a surfactant, a pH adjuster, and an inorganic salt; the solid phase is a composite of fly ash and nano silica; the foam quality is 90%-99%. The solid phase foam stabilizer is a compounded system of fly ash particles and nano silica particles, which is not only low in cost but also can form a stable solid particle adsorption layer on the foam film. Thus the instability of the foam such as film rupture, gas diffusion and bubble aggregation can be greatly reduced, and the stability of the foam can be effectively improved.

Abstract: Described are admixture composition and method for integrally waterproofing cementitious compositions, such as concrete and mortar, wherein an organosilicon compound (e.g., silane) is mixed with animal oil, vegetable oil, or mixture thereof, and defoaming agent. The organosilicon/oil mixtures of the present invention enhances the water repellent efficacy of the organosilicon, even as it displays inherently greater product stability, as compared to emulsion-based (and thus substantial free-water containing) admixture formulations of the prior art. Cementitious materials made in accordance with the present invention demonstrate excellent air consistency and air neutrality.

Abstract: The present invention provides a composition and method for modifying a hydratable cementitious composition such as concrete or mortar using at least three different, distinct carboxylate polymers, even when clay is present in the concrete or mortar that would otherwise diminish dosage efficiency of polycarboxylate polymer used as dispersant. The three polycarboxylate polymers, designated as Polymer I, Polymer II, and Polymer II, are derived from monomer Components A, B, and C wherein Component A is an unsaturated carboxylic acid, Component B is a polyoxyalkylene, and Component C is an unsaturated carboxylate ester. The component molar ratio ranges for A:B:C are different as between Polymers I and II; while a distinct component molar ratio A:B+C is identified for Polymer III. When treated with these three different polycarboxylate polymers, the hydratable cementitious composition is surprisingly enhanced in terms of initial workability and slump retention, especially if clay is present.

Abstract: An aqueous concrete mixture having an air pore volume between 10 and 85%, preferably between 20 and 85%. When the aqueous concrete mixture is cured, a concrete having uniform density and high strength is obtained. This is achieved by including in the concrete mixture an aqueous, anionic surface-active compound containing two sulphonic acid groups of the general formula(R).sub.m --R.sub.1 --(SO.sub.3 M).sub.2 (1)wherein R is an aliphatic group having 4-20 carbon atoms, m is a number 1 or 2, the sum of the number of carbon atoms in the 1 or 2 R groups being 6-30, R.sub.1 is an aromatic group containing at least 2 aromatic rings and 10-20 carbon atoms, and M is a cation or hydrogen. The anionic compound has an air-entraining effect and improves the homogeneity of the concrete mixture.
