The demand for more sustainable building materials has led to the development of systems with self-repairing properties. self-healing technology been shown be effective in concrete and mortars, however, this is not often studied grouts. Cementitious can show an autogenous healing, i.e., intrinsic ability repair microcracks by themselves. This type healing improved addition crystalline admixture...

Abstract Microplastics (particles of plastics <5 mm) affect the physical, biological and hydrological properties agricultural soil, as well crop growth. We investigated effect addition three microplastics (high-density polyethylene (HDPE), polyvinyl chloride (PVC), polystyrene (PS)) at a concentration 5% (w/w) to silty loam soil on selected growth radish ( Raphanus sativus L. var. sativus). ...

This paper presents the autogenic self-healing potential of Portland cement (PC) blends made with conventional supplementary cementitious materials (SCMs), to improve water-tightness by reducing overall pore size. Mortar samples were prepared mixing PC, sand and water, partially replacing PC either silica fume (SF), pulverised fuel ash (PFA), or ground granulated blast-furnace slag (GGBS). Dama...

Several studies have investigated the properties of alkali-activated materials (AAM), considering it as a substitute cementitious concrete. However, on self-consolidating concrete (AASCC) are extremely limited. This paper AASCCs utilizing ground granulated blast furnace slag (GGBFS) main precursor. Single, binary, and ternary were produced using fly ash Class-F (FA) silica fumes (SF) replacemen...

This study regards the development of lightweight geopolymer composites through valorization various construction and demolition wastes. Brick waste was utilized as sole aluminosilicate precursor for geopolymerization reactions, expanded polystyrene polyurethane wastes were used artificial aggregates, short polyethylene fibers developed from CDWs reinforced matrix. The curing conditions synthes...

Despite the growing environmental consequences of cement production, geopolymer concrete now has gradually evolved as an ecologically sustainable product. This study experimentally investigates effect addition different proportions (0%, 10%, and 20%) rice husk ash (RHA) polypropylene (PP) fibers 0.1%, 0.3%) on mechanical durability characteristics fly (FA)-based mortars. The strength property i...

Ferrocement is formed of a thin layer cement mortar that has been strengthened with multiple layers wire mesh diameter between 0.5 mm to 1 mm. To evaluate the durability criteria for specimen, series cubes and cylinders were cast in this experiment using mix at ratio 1:3 water-cement 0.40 was selected. In study, ability ferrocement endure water penetration, sorptivity, resistance sulphates exam...

Zero till is commonly advocated as a preferred cropping system to conventional, multicultivation practices. Zero till is particularly attractive on clay soils, to minimise compaction and induce natural structure formation through shrink±swell cycles. Increases in soil water storage and increased numbers of (bene®cial) soil fauna with zero till have been reported, relative to traditional tillage...
