A factory-made mixture containing in a certain proportion mineral and polymer binders, fillers and modifying (functional) additives for various purposes, used in construction, reconstruction, restoration and major repairs of buildings and structures. According to their purpose, such mixtures can be combined in accordance with the stages of facing work. This association and examples of construction chemical products are available for review.
The other day I was able to attend a seminar conducted by the commercial director of the Maska plant in Novosibirsk for wholesale buyers of dry building mixtures. Having recorded his speech by milestones, I approached him with a proposal to post the most interesting information on the site.
The review provides a classification of compositions for laying ceramics and natural stone, in accordance with the standards: EN 12004 and EN 12002.
According to SNiP 2.03.13-88 “Floors”, a screed (base for a covering) is a floor layer that serves to level the surface of the underlying floor layer or floor, give the floor covering on the floor a given slope, cover various pipelines, distribute loads across the non-rigid underlying floor layers on overlap
Getting acquainted with the characteristics of mixtures based on cement binder, you understand that they are largely determined by the mineralogical composition of Portland cement. In studying this hydraulic binder, I was helped by lecture notes on the discipline “Physico-chemical processes of hardening and corrosion of cement stone” from the Tyumen State Oil and Gas University (TSNU).
The waterproofing layer prevents water from penetrating into the base and prevents its premature destruction. Thus, it serves to strengthen the structure of the structure as a whole, and in some cases protects against corrosion, mold and rot.
