Concrete for industrial floors is a concrete mix used for the construction of floors in industrial warehouses, logistics centres, shopping and entertainment centres, supermarkets, parking lots, etc. Due to special treatment, concrete floors are extremely strong, durable and resistant to mechanical, thermal and chemical loads. Concrete used for application of industrial floors should meet special requirements conditioned by heavy loads that the floor will have to withstand during operation. The surface layer of the cast concrete floor is treated using one of the following methods:Treatment by penetrating liquid agents (impregnates), application of topping coatings or polishing of the floor surface to obtain a uniform matte or glossy finish. Selection of the right grade and class of concrete mix for the construction of industrial floors should involve consideration of compatibility with the above materials, as some treatment agents do not interact with the cement and chemical additives used by the concrete supplier.
Usually, construction engineers select the concrete class most suitable for your construction project themselves. To obtain the concrete mix tailored to suit your specific surface treatment technique, please contact technicians of our factory laboratory and specify the type of topping (or other material) that you plan to use. We offer high quality concrete for pouring of industrial floors, which complies with all relevant requirements and standards. Our managers are ready to provide personal professional advice on choosing the concrete mix to suit your exact needs and your budget, and our highly qualified laboratory technicians can select raw materials and develop a tailor-made mix recipe for applications of any complexity level.
The concrete grade is designated by an alphanumeric code (for example, M-100),which denotes the ultimate compressive strength expressed in kilograms per square centimetre. A higher value means a greater amount of cement in the composition. The grades range from M-50 to M-1000, while the most popular grades are between 100 and 500. The higher the strength grade, the stronger, more frost-resistant and more durable the concrete.
Today, design specifications often define the class of concrete mix, which shows properties of the mix more precisely. The class of concrete mix denotes the permissible deviation from the mix quality. It shows the strength value obtained for an actual sample while the grade shows the estimated strength only. The class of concrete is marked with the letter ‘B’, and ranges from 3.5to 80. Classes B7.5 to B40 are used in domestic construction.
B25 has improved strength, water impermeability, frost resistance, and density and is able to take up significant static and cyclic loads. It is used for concrete casting of foundation slabs, floor slabs, vertical structures, reinforced concrete items, as well as industrial floors that are intended for further topping treatment.
Mixes of class B30 offer increased strength performance. They are used in applications, where the increased strength, waterproofness, and frost resistance are required, including concrete casting of foundation slabs, floor slabs, vertical structures, structural columns, reinforced concrete items, as well as industrial floors that are intended for further topping treatment.
Р3 — workability factor measured by concrete slump test, with a slump of 10-15 cm. The mix is used for the construction of foundations, stairs, screeds, floors and for pouring into form works. This concrete mix must only be poured using special construction tools: vibrating pokers, vibrating screeds, concrete laying machines.
Р4 — workability factor measured by concrete slump test, with a slump of 16-21 cm. The mix is used in applications of any complexity level. Due to good workability (fluidity), it fills a form work completely, so that no pores or air voids are formed. The mix can be transported over a long distance by a concrete pump or a chute system.
