dc.description.abstract Cracks of variable width and types can develop due to various factors like overloading, thermal expansion and contraction, moisture and temperature stresses, poor construction quality, loss of support underneath the slab, and other similar causes. Often a combination of these factors contributes to the propagation and widening of cracks over time resulting in surface roughness if not repaired properly. Wide crack even requires reconstruction or a full-depth repair. Cracks should be repaired with a durable material lasting for longer life. To repair these cracks, several materials and procedures have been developed. The efficiency of these materials and procedures depends on weather conditions and application efficiency. This study aims to develop a cost-effective magnesium oxychloride cement-based micro concrete for a faster repair of wide cracks; 25 mm or more. To simulate the conditions in the laboratory beam specimens cast and tested for flexure strength failure were used. Then broken beams were repaired by laboratory-developed MOC cement-based micro concrete and again tested for flexure strength. It was found that up to about 80% flexure strength can be restored in one day. en_US
