Abstract Damages that often emerge in concrete include cracks, delamination, spalling, wear, fracture, porous, voids (perforated). These damages need to be repaired, one of which is by patch repair. With consideration strength and frugality, a self-made repair material was developed using mortar as base material, i.e., geopolymer mortar. Geopolymer with natural materials have high content silic...

This piece of research was conducted to provide guidance and help theconservation architects for the preparation appropriate lime mortar conservation stonemasonry. A comprehensive detailed examination works on significanthistoric monuments in Lahore carried out Department Archaeology Museums,Pakistan. The results provided analytical description lime, types ofKankar-lime followed by analysis var...

 The performance and durability of concrete in construction is essential to maintain the sustainability protection material. Particularly marine environments, attack aggressive chemical compounds can affect accelerate deterioration. This research aims improve environments by using additional methods such as Surface Applied Protection. One materials used geopolymer mortar that uses ...

Attentive monitoring and regular repair of concrete cracks are necessary to avoid further durability problems. As an alternative to current maintenance methods, intrinsic repair systems which enable self-healing of cracks have been investigated. Exploiting microbial induced CaCO3 precipitation (MICP) using (protected) axenic cultures is one of the proposed methods. Yet, only a few of the sugges...

Cracking is one of the most severe problems facing the concrete industry worldwide. Of critical importance is the drastic decline of durability associated with these cracks, and the resulting cost of repair or replacement of concrete structures. This research examines the effect of crack width and crack frequency upon the durability of reinforced mortar, quantified by water permeability. Crack ...

An unsaturated polyester resin (UPR) mortar was applied to repair the damage tension zone's one-way reinforced concrete (RC) slabs. The load carrying capacity of patched RC slab is interest justify effectiveness repair. Yield Line Theory (YLT) may be used estimate slabs under concentrated load. results YLT are compared with experimental evaluate validity method. confirm that patching alters yie...

As the urban population increases and level of social life advances, amount wastewater originating from houses, institutions industries as well. It is necessary for infrastructure systems in settlements to be sustained under healthy conditions. Since subsequent repair difficult, appropriate selection materials used these importance. Concrete pipes are widely sewerage systems. In present study, ...

Reliable design and application of textile-reinforced mortar (TRM) composites for the repair existing masonry concrete structures requires a fundamental understanding textile-to-mortar bond behavior as one main mechanisms controlling their nonlinear response cracking behavior. Suitable test setups analytical models are needed to extract bond-slip laws from experimental pull-out tests. This pape...
