PERFORMANCE GRADE ASPHALT REPAIR COMPOSITION
The present invention is a system for repairing asphalt. The system includes a discrete quantity of an asphalt repair composition located within a container and an induction heater. The composition is a combination of an asphalt binder, aggregate particles, and induction particles. The average diameter of the induction particles ranges from approximately 10% above to approximately 10% below an average diameter of the aggregate particles used in the composition. The induction heater heats the composition within the container by generating a magnetic field that penetrates the container. The magnetic field creates eddy currents in the induction particles. These eddy currents in turn heat the composition. Because the induction particles are distributed throughout the composition, the composition heats rapidly.
ULTRA-FAST SETTING CEMENT BASED ON AMORPHOUS CALCIUM ALUMINATE
The present invention relates to an ultra-fast setting cement composition containing at least amorphous calcium aluminate including by weight, as compared to amorphous calcium aluminate total weight: (a) from 35 to 55% of calcium oxide CaO (C), (b) from 19 to 55% of alumina Al.sub.2O.sub.3 (A),
the C/A molar ratio being higher than or equal to 1.5, (c) from 0 to 10% of silica SiO.sub.2,
with the amorphous calcium aluminate including (d) from 5 to 16% of iron oxide Fe.sub.2O.sub.3. Also disclosed is a method to produce the cement composition, as well as to uses thereof.
TYPE OF GLASS-BASED CONCRETE AND PREPARATION METHOD THEREOF
A glass-based concrete includes in parts by mass: 25 to 35 parts of a glass material, 15 to 25 parts of fine aggregate, 33 to 45 parts of coarse aggregate, and 1 to 5 parts of a fluxing agent. A method for preparing a glass-based concrete includes steps of: S1. mixing raw materials according to the above parts by mass: 25 to 35 parts of a glass material, 15 to 25 parts of fine aggregate, 33 to 45 parts of coarse aggregate, and 1 to 5 parts of a fluxing agent; S2. putting the mixture into a high-temperature furnace, setting temperature, and heating to melt to form a uniform and bubble-free liquid glass-based concrete; and, S3. pouring the liquid glass-based concrete into a mold for cooling and molding. The glass-based concrete of the present invention is characterized by high strength, low energy consumption and low carbon emission.
Methods and compositions to increase performance of asphalt cement concrete comprising recycled asphalt pavement
The Present disclosure is related to hot-mix asphalt (HMA) for asphalt cement concrete (ACC) pavement. Equivalent-performing pavement may be made at lower cost, or higher-performing pavement may be made at equivalent-to-prior-art cost. The amendments, recycled asphalt pavement (RAP, and including recycled asphalt shingles [RAS]), and reinforcing fiber (aramid fiber) may be adjusted as described herein to achieve a desired price/performance target.
