As we know that Indonesia has two seasons, namely the rainy season and the dry season (dry), this can hinder a process where fresh concrete in the dry season the concrete can dehydrate and in the rainy season if there is too much fresh concrete water will occur the concrete will be too runny and not workbility and can delegate on fresh concrete.To speed up the drying of concrete, additional materials are needed for the concrete mix, both chemical and mineral materials.There are various forms.Some are in the form of solid powder or liquid.Chemically, these additives will have an impact on the properties and characteristics of the concrete mix.Basically, there are 3 types of concrete additives according to their function.The first is an additional material to accelerate the drying of concrete which is mostly applied to water structures.The second is an additive to slow down the drying of concrete which is usually used for hard-to-reach terrain.And the third is additional material to reduce water use.So how to make concrete dry quickly?The main key is that we need an additional material that can shorten the drying time of the concrete mix.One of them is plasticizer or also known as water reducing admixtures.Generally these materials work by reducing the water content in the concrete mix so as to produce concrete with a certain consistency. Plasticizer (Water Reducing Admixtures)Plasticizer (water reducing admixtures) is a useful additive to speed up the drying process of concrete.This material will reduce the water content contained in the concrete mix so that it can produce concrete with a certain consistency.In Indonesia, there are several brands of plasticizer products that have water reducing capabilities.The application of plasticizer additives can be applied to high-quality concrete construction projects that require faster drying times.The dose used is around 130-265 ml of plasticizer per 100 kg of cement depending on needs.Although the time for making concrete can be made faster, you have to be careful because there is a risk that the concrete will crack due to the abnormal drying process.Cracked concrete causes the structure to become porous, not strong, and easy to collapse.Therefore, other additional materials are needed that can prevent the risk of cracking in the concrete.Among them are calbond and calflash.CalbondCalbond is a plastic-based concrete adhesive.The main function of this material is to connect the old concrete with the new concrete and help glue the plaster to the brickwork.Calbond can also be used to repair cracked walls and assist in the ceramic installation process.Some people also often refer to calbond as concrete glue.How to use calbond is basically very easy.If you want to use it to join old concrete and new concrete, then you have to apply this material to the concrete surface first and wait for it for 15 minutes.Only then proceed with the casting or plastering process.Meanwhile, if you want to use it to continue the stopped casting process, calbond must be mixed with cement and water until the consistency is like paint.Then pour the mixture onto the surface of the cast. CalflashCalflash has a function to patch leak holes in concrete.If not repaired immediately, the hole will have a negative impact on the building and its contents.The size of the hole will gradually get bigger.This case often occurs in underground water reservoirs, machine foundations, dams, basement spaces, and others.
