Abstract

Revised 2/6/60 The production process of marine primer ready-mixed concrete is intended to bring raw materials of production Marine concrete is mixed according to a specific process by a specific performance mixer starting with the preparation of a concrete mixer with a clean interior. Weigh the largest rock size 19.0 mm and put cement into it. In a concrete mixer Then turn on the machine to mix the stone and sand and cement into a homogeneous mixture when the ingredients are thoroughly mixed. Then add all the water used to mix When the added water is mixed well with sand, stone and cement. Therefore began to add 1.05 liters of concrete admixture per cubic meter and turn on the concrete mixer so that the added solution mixes well with the concrete mixture for 30 seconds, then the mixing process is completed ......... .................................................. .................................................. .......................................... The production process of marine ready-mixed concrete is intended to use raw materials of production. Marine concrete is mixed according to a specific process by a specific performance mixer starting with the preparation of a concrete mixer inside that is clean. Weigh the stones up to 6.0 mm. And cement into the Concrete mixer Then turn on the machine to mix the stone and sand and cement into a homogeneous mixture when the ingredients are thoroughly mixed. Then add all the water used to mix When the added water is mixed well with sand, stone and cement. Therefore began to add concrete admixtures in the amount of 1.05 liters per cubic meter Ready to turn on Mix the concrete so that the added solution blends well with the concrete mix, for 30 seconds to complete the mixing process.
