Mechanical Properties and Resistance to Water Ingress of Cement Concrete Made with Non-Cyclic Alkanes

Abstract:

The goal of presented research is an assessment of fundamental mechanical properties and resistance to water ingress of concrete with non-cyclic alkanes. Compressive and tensile strength, water absorption capacity and sorptivity of concrete made with and without an admixture of non-cyclic alkanes has been analysed. The paraffin enriched concretes have been made with 1% (C1F and C1C) and 3% (C3F and C3C) volume addition of paraffin wax. The paraffin wax has been used in two grades of comminution: fine (FP) in CxF concretes and coarse (CP) in CxC concretes. A significant (35%) loss of compressive strength of concretes with admixtures has been noticed and no loss in tensile strength was observed. Up to 25% of water absorption capacity reduction and irrefutable (8 times) sorptivity reduction has been also noticed, but only in the case of concrete made with admixture of FP.
