Everything you need to know about concrete lubricant
Lubricant is a chemical additive in concrete that is used as a water reducer and to increase the slump of concrete. Obviously, as the number of slumps increases, the concrete becomes smoother without the concrete losing its properties, making it easier to fill the pores of the poured area. In this article, we try to understand what concrete lubricant is and get acquainted with its different types and applications. Join us.
. Advantages of concrete lubricant
The advantages of concrete lubricant include the following:
Increase the number of slump and flow of concrete
Water reducer
Cement grade reduction
Increase compressive strength
Can be used in concretes with unsuitable aggregates
Can be used in thin and full rebar molds
Ability to pump concrete
Advantages and disadvantages of concrete lubricant
Disadvantages of concrete lubricant; As the recommended amount of lubricants in the concrete mix increases, we will usually see more watering, more separation and slowing down. Excessive watering causes the concrete to disintegrate. Excessive use of these additives usually slows down the concrete. Determining the optimal amount of use of these additives should be based on the values proposed by the concrete lubricant manufacturer and by making a test mixing plan using the materials used in the project. The use of some of these additives causes air bubbles in the concrete and this issue should always be considered in the use of these chemical additives. The constituents of these concrete additives are mainly organic compounds that can delay the setting time of concrete. To be. To compensate for this problem, some of these additives use small amounts of accelerating compounds.
