Admixtures that affect the work ability of a concrete combination will also affect the slump, which is a test of the consistency of the mix. The slump of a mix with the same aggregate, cement and water can very significantly by adding an admixture such as a high-range water-reducing admixture, which will increase the strength and provide greatly increased workability with the addition of excessive amounts of water. The admixture does not reduce the quality of the material bubbles are entrained in concrete using an air-entraining
