1. Thickness and rebound loss of bond damage The incorporation of silica fume in shotcrete can improve the adhesion to the bonded surface and the cohesion within the shotcrete; thus the thickness of shotcrete on the top and vertical surfaces can be greatly increased. In the study of wet mix shotcrete , if not mixed with silica fume, the top surface of the bond damage thickness of 90 mm; if mixed with compacted low-density silica fume, the maximum value of up to 280 mm. the top surface of the bond damage thickness is generally greater in dry mix shotcrete, if mixed with non-compacted silica fume, the maximum value of dry mix shotcrete up to 380 mm, while the top surface of dry mix shotcrete without silica fume The top surface rebound of dry shotcrete is 42.7% for shotcrete without silica fume, which can be reduced to 21.4% with the addition of silica fume. The amount of springback on the vertical surface: 45.5% for shotcrete without silica fume; can be reduced to 22.8% with the additio...

Introduction Green silicon carbide is made of petroleum coke and high quality silica as the main raw material, adding salt as an additive, and smelted by resistance furnace at high temperature. Production Process Green silicon carbide is used for processing cemented carbide, glass, ceramics and non-metallic materials, as well as for semiconductor materials, high-temperature silicon-carbon rod heaters, far-infrared source substrates, etc. Green silicon carbide is manufactured in the same way as black silicon carbide , but the purity of the raw material used is higher, and it is also formed at a high temperature of about 2200°C in a resistance furnace, green, translucent and hexagonal in shape, with a higher Sic content than black. Applications Green silicon carbide is an inorganic salt compound with the following applications. 1, applied in the non-ferrous metal smelting industry. With green silicon carbide high temperature, strength, good thermal conductivity and impact resistance, hi...

Large commercial concrete mixing station after delivery to the user scene, then into concrete mixing plant equipment installation and debugging, the core stage, how to effectively guarantee the future installation of concrete mixing station low failure rate, and deal with small problems such factors, all need to users and large concrete mixing plant equipment understanding factory technical person When debugging control system to reset the emergency button, closed electric power contained in the public, after connect on each branch circuit breaker, control circuit, power supply switches, control the power switch, observe the electrical system if there is any abnormal phenomenon, if have immediately check; Open the button of each motor and test run of the motor to correct, if not correct should immediately adjust; Start the pump concrete mixing station, after waiting for air pressure is achieved according to the button labeled start each pneumatic door, check whether the action is...
