Production of concrete
Our company has a concrete mixing plant for the production of bulk concrete and road concrete type Liebherr, type BETOMAT II-345, located in Popeşti-Leordeni, Ring Road, no. 111. The AAS3 Concrete Bulk Classification Nomenclature includes concrete classes C8 / 10 to C50 / 60, and the class of road concrete classes ranges from BcR 3.5 to BcR 5.0. The concrete mixing plant is equipped with two forced mixers, one that provides a production capacity of 100 MCH for the delivery of concrete in the construction site and the second, which provides a production capacity of 55 MCH for the delivery of concrete required for casting prefabricated elements in their own hall. The concrete mixing plant is equipped with a centralized heating system for hot water and an aggregate heating system, which allows concrete to be delivered even in cold weather. The conveyance of the concrete products is provided by the company’s fleet, made up of MAN concrete mixers and Mercedes model, with a capacity of 9 cubic meters, and the commissioning of the fluid concrete is carried out with the help of the Putzmeister model, with a boom length of 36 m. According to the company’s integrated management system, we are particularly concerned with ensuring regulatory requirements for environmental protection and recycling of water from flushing of mixers or concrete mixers as well as fresh concrete from accidental or reinforced concrete from the maintenance of the mixers or as residue from the tests carried out in the own laboratory.
Production of prefabricated concrete elements Administration Active Sector 3 S.R.L. owns a factory of precast concrete elements located in Popeşti-Leordeni, Ring Road, no. 111, consisting of a production hall where the reinforcement processes are carried out on the one hand and on the other hand the technological processes of casting of concrete in the formworks with reinforcements, for various types of prefabricated elements, are made.The prefabricated factory is equipped with advanced technological lines, as follows:· Concrete mixer with forced mixing, LIEBHERR model; Various patterns; Equipment for cutting, bending, shaping and welding of reinforcements; Stator pretensioners.
