Self-compacting mortars are achieving a great deal in the construction industry due to their remarkable characteristics and advantages over conventional concrete. The main drawback associated with self-compacting is high cost ingredients used production of mortars. This research aims overcome this by combining effects nano-silica glass powder on properties mortar at normal higher temperatures. ...

This study investigated the fresh, physical, and mechanical properties of self-compacting geopolymer mortars (SCGs) with synthetic wollastonite microfiber (SWM). SCGs were designed Class F fly ash (FA) as a binder by activating it Na2SiO3 NaOH solutions. First, SWM was produced in laboratory. Alkali ratios determined 1.5, 2.0, 2.5, whereas percentages utilized 0%, 4%, 8%, 12% weight binder. Aft...

Reinforced Autoclaved Aerated Concrete (RAAC) was a very common form of construction in the UK and elsewhere 1970s, many buildings are now coming to end their design life. Although much is known regarding new RAAC (and AAC), concerns exist durability, hence current structural integrity 40-50 year old panels, which use critical infrastructure such as hospitals, schools government buildings. Anec...

Self-Compacting Concrete (SCC), a high-performance concrete with exceptional fluidity and cohesiveness, has gained popularity recently. The consolidation qualities durability demands of this material require the application Supplemental Cementitious Materials (SCMs). Alccofine is type additive that potential to increase SCC characteristics while lowering environmental effect Portland cement man...

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, ...

FABA is a by-product of coal combustion in power plants comprising fly ash (FA) and bottom (BA) ratios 80/20. Fly has great potential as mineral ingredient concrete, while compromises its strength durability. However, both materials are used to improve the durability structures sulfate, chloride, acidic environments. This research evaluated properties blended high-volume such strength, porosity...

Abstract One of the challenges promoting accelerated carbonation curing (ACC) concrete as a carbon sequestration strategy is ensuring that will not deteriorate mechanical strength. This study examined strength, water sorptivity and efficiency ten types mortar containing dry or pre-soaked biochar subjected to internal and/or external carbonation. The results obtained enabled typology ACC be prop...

Cracking of concrete, which may be induced by several mechanisms, such as shrinkage, thermal effect, and loading, plays an important role in the deterioration of reinforced concrete structures because they provide additional pathways for water and aggressive agents, for example, chlorides, to penetrate into concrete. To well understand the transport properties of cracked/damaged concrete is ess...

It is well-known that supplementary cementitious materials (SCMs) and low water-to-binder (w/b) ratio increase autogenous shrinkage, but the impact on microcracking long-term transport properties less understood. This paper examines effect of induced by shrinkage concretes cured up to ~3.6 years. Variables include SCM type (9% SF, 70% GGBS), w/b (0.20–0.45), maximum-aggregate-size (MSA: 5–20 mm...
