This paper presents the results of experimental and analytical studies mechanical thermal properties laterite composites mixed with reprocessed low-density polyethylene waste (LDPE), calcium phosphate (CaP) phosphogypsum wastes, biochar to form brick composites. Bricks mixtures 20% by volume LDPE, 15% CaP, gypsum were shown have excellent compressive strength, flexural fracture toughness. The 1...

abstract statement of problem: mechanical strength and durability of dental composites are the main topics studied in this field of science today. this study examined fumed silica-based composite as a strong and durable restorative material through flexural and cycling test methods.     objectives: the purpose of this study was to evaluate the effect of silanization, ageing, cycling and hybridi...

The (brittle) behavior of concrete, although used in many fields, impedes its use some applications that require (flexible) behavior, wherefore several types fibers were utilized among them polypropylene fiber (PPF), enhances pre-crack tensile strength, toughness, ductility performance, impact resistance, flexural strength and failure mode. This paper submits a comprehensive review previous stu...

Strain hardening geopolymer composite (SHGC) is a tailored group of sustainable high-performance fibre reinforced composites with strain behaviour and ultra-high ductility. This paper experimentally investigates the effect fine silica sand content (0–40% by weight binder) on engineering properties fly ash-slag based SHGC cured at ambient temperature, including workability, setting time, drying ...

Owing to high density, concrete paving blocks (CPB) are highly brittle when subjected occasional impact loads. Fractures in CPB create riding discomfort and increase maintenance costs. This issue demands the engineering design of suitable for dynamic loadings. Therefore, this study explores effect eco-friendly cheap fiber recycled from scrape tire steel on performance blocks. For purpose, sever...

To improve the economic benefits of engineered cementitious composites and control repair cycle, materials were designed, with key components mixture being low-cost polypropylene (PP) fibers fast-setting sulfoaluminate cement. The effects water/binder ratio, fiber content, aggregate particle size on flowability, mechanical properties, toughness fiber-reinforced composite (PP-SACC) explored. Bas...

Abstract Squeeze casting and powder metallurgy techniques were employed to fabricate AlSi12/Al 2 O 3 composites, which are lightweight structural materials with potential applications in the automotive industry. The impact of processing route on material properties was studied. Comparative analyses conducted for Vickers hardness, flexural strength, fracture toughness, thermal conductivity, resi...
