Publicity to cement dust may result in concerns for instance silicosis, kidney illness, pores and skin discomfort and comparable outcomes. The U.S. Countrywide Institute for Occupational Basic safety and Health in The us suggests attaching local exhaust ventilation shrouds to electric powered concrete grinders to regulate the spread of this dust. On top of that, the Occupational Basic safety and Wellness Administration (OSHA) has positioned a lot more stringent rules on companies whose staff consistently appear into Speak to with silica dust. An up to date silica rule, which OSHA place into influence 23 September 2017 for development firms, restricted the quantity of breathable crystalline silica staff could legally come into Speak to with to 50 micro grams per cubic meter of air ห้างหุ้นส่วนจำกัดสหคอนกรีตอัดแรง for every eight-hour workday.

Most structural concrete is poured with reinforcing products (including steel rebar) embedded to offer tensile strength, yielding reinforced concrete.
