This invention relates to a pretreated reinforced recycled aggregate concrete and its preparation method, comprising the following raw materials: 320-360 parts cement; 20-40 parts fly ash; 80-120 parts mineral powder; 585-670 parts manufactured sand; 1050-1200 parts recycled coarse aggregate; 156-172 parts water; and 11-12.3 parts admixtures. After pretreatment, the concrete prepared from the recycled coarse aggregate exhibits significantly improved performance compared to the untreated recycled coarse aggregate. The synergistic effect of multiple pretreatment methods significantly improves the water absorption, crushing index, and apparent density of the raw coarse aggregate. Pretreatment of the recycled coarse aggregate provides enhanced conditions for internal hydration in the recycled concrete and simultaneously improves the surface roughness of the recycled coarse aggregate, thus enhancing the workability and increasing the strength of the concrete.

The application belongs to the technical field of road engineering, and particularly relates to a production process of modified emulsified asphalt. The process comprises the following steps: preparation of a soap solution: water is added to a reaction container, heated, stirred after the addition of an emulsifier, an emulsifying aid, and an acid-base regulator to adjust pH, and the soap solution is obtained; modification of asphalt: base asphalt is added to a shearing grinder, heated to 165-220 DEG C, reacted after the addition of an SBS modifier, a compatibilizer, and an aid, and the modified asphalt is obtained; and emulsification of the modified asphalt: the prepared soap solution and the prepared modified asphalt are added to a colloid mill, heated, and emulsified, and the modified emulsified asphalt product is obtained after cooling. The emulsifier composed of a cationic surfactant as the main component, a nonionic surfactant, and a small amount of an anionic surfactant can enhance the emulsification performance of the system, improve the storage stability of the emulsified asphalt, and effectively improve the high and low temperature performance of the emulsified asphalt.

This invention discloses an injection molding die for PVC pipe fittings, belonging to the field of injection molding technology. It includes: a fixed mold base with a first water-cooling plate fixed to one end face; a sliding mold base, parallel to one side of the fixed mold base; a fixed template, installed on the end face of the first water-cooling plate near the sliding mold base; a movable template, fixed to the side of the sliding mold base near the fixed template; two mold cavities, symmetrically arranged in the fixed template; and two core guide units, each installed in one of the mold cavities on the fixed template. In this invention, the fixed template and the movable template can fit tightly together to form two injection molding cavities for the PVC pipe fittings. The core shaft in the main shaft core device can be eccentrically or coaxially distributed with the mold cavity as the shaft rotates, which facilitates rapid filling of the mold with PVC material, shortens the injection cycle, prevents material shortages or incomplete filling due to flow obstruction, and improves product quality.
