Self compacting concrete SCC Pars Laneh

The most important advantage of SCC is high flow ability and high resistance to separation. The flow ability property of concrete itself is the result of changes in the design of ordinary concrete mixes. These changes are achieved by the use of large amounts of powder (cement, rock powder and mineral additives), new generation lubricants and viscosity modifying additives. Accurate selection of aggregate volume and proper aggregation are also essential to the concrete mixing plan itself.

Benefits of SCC concrete:

• Ability to flow between dense bars and in complex molds
• Reduced construction cost due to the need for vibration and less surface finishing operations
• Greater flexibility in mold casting and therefore less need for multiple concreting points
• Achieve uniform and homogeneous concrete and thus improve mechanical properties and durability
• Reduce noise pollution due to vibration removal
• Greater speed in construction due to reduced vibration time
• Improving the surface of the concrete surrounding the mold and thus removing the repair to remove the surface pores
• Reduce the amount of cement with the proper mix design based on the aggregation density

Disadvantages of SCC concrete:

• Increase the cost of molds due to a possible increase in pressure on the mold
• The need for skilled human resources when selecting materials, mixing designs, performing tests and performing
• Increased risk and uncertainty due to the use of new materials such as new generation of lubricant, viscosity modifier and rock powder
• Increased quality control requirements
• The probability of major changes in the properties of fresh and hardened concrete due to the slightest change in the type and amount of consumables
