Repair materials have been developed in this research by adding micro-synthetic fibers cement-based mortar. In addition, accelerator is incorporated the mortar to obtain high early strength of repair materials. Their shrinkage behavior interest. This study aims determine fiber-reinforced and propose models reflect their behavior. The results show that rapid developments are observed at an age w...

The ureolytic bacteria and nutrients were immobilized in the artificial functional carrier (AFC) self-healing cement mortar, based on AFC-encapsulated bacteria, was prepared for this paper. crack effect of mortars with without under different exposure environments (standard curing, dry–wet cycle water curing) investigated by visual observation surface internal cracks, permeability tests, mechan...

Concrete patch repair has long been used to repair the damaged concrete structures. In cold regions, freeze– thaw cycle is one of the major damage factors. Not only the material itself is damaged by freeze–thaw cycles, but also the adhesive interface, which is regarded as the weakest part of composite system, degrades under freeze–thaw cycles. Air entraining agent has long been used to increase...

Andesite rock is commonly used as a heritage building in Southeast Asia, especially Indonesia. However, the study on consolidation of andesite still limited. This aimed to evaluate application effectiveness TEOS-based material type materials. TEOS was modular system with powder form mortar. andesite-TEOS mortar applied conservation techniques, for gap and joint filling. 
 successfully rock...

Cement mortar is used as a conglomerate in the majority of construction work. There are multiple variants of cement according to the type of aggregate used in its fabrication. One of the major problems that occurs while working with this type of material is the excessive loss of moisture during cement hydration (setting and hardening), known as shrinkage, which provokes a great number of constr...

Using a rejuvenator to improve the performance of asphalt pavement is an effective and economic way of hot asphalt recycling. This research analyzes the rejuvenating effect on aged asphalt by means of a Mortar Transfer Ratio (MTR) test, which concerns the ratio of asphalt mortar that moves from recycled aggregates (RAP aggregates) to fresh added aggregates when aged asphalt is treated with a re...

Ground Granulated Blast furnace Slag (GGBS), a waste product from steel plants, can be effectively utilized as pozzolanic material and used partial replacement to cement leading sustainable construction practice. Mortar is usually binding plastering material; hence the chances of exposure damaging environment are high than concrete. GGBS mortar should examined for durability weathering action, ...
