Strengthening the historical constructions made of limestone by treating with silicic acid based material

Abstract

The paper a comparative study of limestones treated with the composition Oxal NK100 for increasing the durability of the limestones in historical buildings and the other limestones without any additives to investigate the effect of the composition Oxal Nk100 on the durability of the investigated stones. Results of frost resistant test and compressive test of different samples are included and analyzed . Indicators charts and diagrams are given included and explained.
