Ready-mixed concrete enterprise command center is stirred computer operation room floor, there is generally a scheduler, an operator and a stirring laboratory staff. Ready-mixed concrete business is a 24-hour operation, long working hours, work intensity, operating room have telephone, radio, GPS monitoring and other facilities, subject to interference, operator fatigue easily. Just by opening a new site operator input with input error prone than the risk to the enterprise has brought huge economic losses.
First, strengthen the quality of education and to increase a stirring operator; the second is to do concrete work opening identify and establish special ledger. Entered by the operator mix, lab mix who is responsible for the supervision and inspection result input, two ledger after signing retention results in increased traceability. This is the approach adopted by the majority of ready-mixed concrete business.
Sodium lignosulphonate, sodium gluconate, sodium naphthalene
(1) strictly control the material properties detected by the above factors to reduce water consumption.
(2) increase the admixture content or use of a high efficiency water-reducing admixture rate, choose better adaptability of admixtures and cement varieties.
(3) improve the gravel grading, to find the best mix for each graded gravel to improve the workability, thereby reducing water consumption.
(4) by using a high content of cementitious materials to improve the workability.
(5) Notwithstanding the silo should be stamped repeatedly detect sand moisture content, to strengthen the sense of responsibility to ensure that every plate a slump concrete machine within the control range.
(6) to communicate with the site construction side is very important to get more understanding of construction workers and technical staff with the construction side to avoid the slump is too large. Correct understanding: Not greater the slump, the easier it will be pumping, but workability and gravel should be adjusted to adjust the amount.
(7) when the actual production is usually water and again with water will vary greatly. Therefore, in strict accordance with the content selection test better than or close to the material, compared with a more stringent test water-cement ratio control, to ensure there is enough surplus strength, and help ensure the site is qualified to enter the final. Try to maintain production with the principles of better.
Concrete additives: sodium lignosulphonate, sodium gluconate, sodium naphthalene formaldehyde, calcium lignosulphonate.
Spring and autumn are some of the common areas in Huaian, the first larger temperature difference between day and night, less rainfall, wind speed larger, generally in 4 to 5, the air drying humidity is small (generally <30%). These bring shrinkage cracks often dried, or a host of other issues to concrete.
Summer is the year continuous high temperature, more complex changes confront a season; hot summer, large evaporation of water, fresh concrete appears dry fast (surface), setting speed, false condensate, condensate duration, lower intensity, etc., and will bring crack phenomenon, which affects the quality of concrete.
