What is concrete and what are its tests? – Part 1

Concrete is the name given to the material resulting from the appropriate mixture, known as mix ratio, of cement, water, coarse aggregate (gravel) and fine aggregate (sand). The composition of this material with steel bars generates the reinforced concrete.  When in its plastic or fresh state, concrete can be molded in desired shapes and dimensions. On the other hand, when...

Risk Assessments on Belt Conveyors

Risk assessments on belt conveyors are extremely important for reliable operation in general. According to international standards, which aim to establish the elements and procedures for risk management, risk can be defined as the result of uncertainty in the expected objectives. Uncertainty, in turn, consists of the absence of concrete data regarding an event, its understanding, the probability of its...
