Quality control (QC) issues in concrete

National Concrete Accessories products are manufactured according to strict specifications and are subject to numerous tests under a stringent quality control program. These products are designed to be capable of meeting or exceeding all necessary safety requirements for the concrete construction, anchoring and forming industry.

Mar 2005 - Apr 20105 years 2 months. Supervision and planning out of tests that were undertaken by the senior and junior technicians on a day to day basis. Reported and liaised with project managers and section engineers with regard to test requirements for the project and reporting the test results.

Recycled aggregate is essential to protect Jeju Island's natural environment, but waste concrete, including porous basalt, is a factor that lowers the quality of recycled aggregate.

Manufacturers with quality control procedures in place are far less likely to face product recalls or place customers at risk from poorly made products. The cost associated with these recalls can be steep. Testament to this is the Takata recall, which is estimated to cost the company between $7 and $24 billion.

Answer: Basalt, as a common non-metallic ore in sand aggregate industry, is widely applied in in construction, bridge, road construction and other industries. Basalt is hard and tough material with high abrasion resistance and high silicon content. It is difficult to be crushed and with high crus...
