TH12704C3 - Production process for large-diameter ready-mixed concrete - Google Patents

Abstract

Revised 24/11/16 The production process for large-diameter needle-punched concrete was started by preparing a concrete mixer at The interior is clean and the interior surface is wet. (Completely dry wood) and aggregates (stone and sand) containing moisture. In the saturated state with water and dry surface, weigh the stone and cement into the concrete mixer. Then turn on the machine to A homogeneous mixture of stone and sand and cement is mixed in a mixer. When the ingredients are well mixed together. To weigh the fly ash, then add all the water used to mix. Once the added water is mixed well with the sand, stone and cement, the concrete mixer will begin to be added and the concrete mixer is turned on to allow the added solution to be compatible with the Concrete mixture, thus completing the mixing process. .................................................. .................................................. .................................................. The production process of large-diameter ready-mixed concrete starts from preparing a concrete mixer that The interior is clean and the interior surface is wet. (Not completely dry) and aggregates (stone and sand) with moisture. In a state saturated with water and dry surface, weigh rocks and cement. Put into the concrete mixer Then turn on the power With one speed To mix the stone and sand and cement into a homogeneous mixture in a mixer when the cement, sand and stone are well mixed. To weigh the fly ash and then add all the water. However, while adding water Turn on the concrete mixer so that the added water mixes well with the sand and cement mixture. When the water is added down Mix well with sand, stone and cement. Therefore began to add concrete mixtures Ready to turn on the concrete mixer In order for the added solution to blend well with the concrete mix, the mixing process is completed.

Disclaimer (all), which will not appear on the advertisement page: Amendment 24/11/16 1. Production process for large-diameter needle-punched concrete has the following steps: a. Prepare a concrete mixer with clean interior. And that the internal surface is wet (Not completely dry) and aggregates (rock and sand) with moisture in the state of saturated water and dry surface (saturated surface dry) b. Weighing rock size up to 19.0 ml, volume equal to 1145 kg / m3. And cement 365 kg / m3 Put into the concrete mixer Then turn on the machine at 20 revolutions per minute to mix the stone and sand and cement homogeneously in the mixer for 1 minute and 30 seconds. C. When the cement, sand and stone are mixed well. To weigh the fly ash in the amount of 90 kilograms per cubic meter and then add all the water. However, while adding water, turn on the concrete mixer to allow the added water. Goes well with sand and cement mixture for 1 minute. D. When the added water is mixed well with sand, stone and cement. Therefore began to add concrete admixture volume 2.15 liters per cubic meter Ready to turn on the grate mixer to make the added solution mix well with the mixture of Concrete for 30 seconds to complete the mixing process. 2. Large needle-punched ready-mixed concrete according to claim 1, where the mixing ratio formula is as follows: The amount of cement is 365 kilograms per cubic meter. The fly ash content is 90 kg / m3. The amount of water mixed with concrete is 145 kg per cubic meter. The amount of sand is 810 kilograms per cubic meter, the rock volume is 1145 kilograms per cubic meter. The volume of concrete admixture is 2.51 liters per cubic meter. .................................................. .................................................. .................................................. .................. 1. The production process of large-diameter ready-mixed concrete has the following steps: a. Prepare a concrete mixer that is clean inside and the inside surface is wet. (Not completely dry) and aggregates (rock and sand) with moisture in the state of saturated water and dry surface (saturated surface dry). B. Weighing rock size 19.0 mm, volume equal to 1145 kg / m3. And 365 kg of cement per cubic meter Put into the concrete mixer Then turn on the machine at 20 revolutions per minute to mix the stone and sand and cement homogeneously in the mixer for 1 minute and 30 seconds. C. When the cement, sand and stone are mixed well. To weigh the fly ash in the amount of 90 kilograms per cubic meter and then add all the water.
