In addition to solutions for the construction of cement and cementitious components use different fillers. Their main purpose - to reduce the consumption of cement and form a solidified mass frame. There are different formulations of mortars and concretes, each of which has its own operational and formulation properties. Do you know which way you can reduce the cost of the solution if the construction budget is low? What factors influence the composition of the components depending on the purpose of the construction work? By answering our test questions, you will be able to verify their competence in this area.
