Curable Nepheline-Based Subgrade Mixtures With Hypsum-Anhydrite Additives
Abstract
The paper presents research carried out into mechanical-and-physical properties of subgrade mixtures based on nepheline binding materials produced by the alumina industry. It is shown that gypsum-anhydrite waste included in nepheline binding material has an effect on strength, water absorption and frost resistance of curable subgrade mixtures. While introducing 5 % gypsum-anhydrite waste in the subgrade mixture, the strength of material under pressure increases by 2,4 times after 28-day ageing and the F25 brand frost resistance is provided.
