Concrete with cactus is a new type of concrete high fluidity, strength, and durability more remarkable advantages. The present paper discusses the role Euphorbia tortilis (ETC) to achieve durability, corrosion resistance properties specimens. In this work, M20 (2900psi) was designed as per Indian standards, were used an additive. ETC extracts from Tamilnadu (India) replaced water (1%, 3%, 5%, 7...

The application of waste materials in the concrete composite is a great contribution to preserving natural resources and enhancing sustainable greener development construction industry. This study used Palm Oil Clinker (POC) steel fibers manufacture high-strength lightweight (HSLWC). POC basically byproduct palm oil industry, which was utilized as coarse aggregates supplementary cementitious co...

Abstract Retrofitting thermal insulation to solid masonry walls alters their hygrothermal behaviour, which can be modelled by simulation software. However, such software needs values of key material properties ensure satisfactory results and until now data has not been available for Scottish buildings. This work aims contribute a Scotland-specific dataset use designers working on Thermal conduc...

Objectives: The intent of the study is to assess strength and durability behavior concrete specimens attaining micro fillers such as alccofine zeolite reinforcement in form polypropylene fibres. Methods: Polypropylene fibres were added volume fractions 0%,0.1%, 0.2%, 0.3% 0.4%. mechanical properties compressive strength, modulus elasticity flexural obtained for mixes with without PP through sta...

This study focuses on the evaluation of efficiency a low-cost macrocapsule, using commercially available pharmaceutical capsules with specific modifications, for self-healing concrete. The macrocapsules were developed by Belgian Building Research Institute in previous study. healing agent is resin based alkyd-urethane, commercial product, which was selected its compatibility concrete and shell,...

The focus of this study is to investigate the effect using coarse recycled concrete aggregates (RCAs) as an alternative material natural aggregate on fresh, mechanical and durability behavior reinforced with steel fiber. Eighteen unique mixes RCA content 0%, 50%, 100% fiber 1%, 2% were prepared, tests performed slump, density, compressive splitting tensile strengths, flexural behavior, surface ...

Background: Concrete is the most widely used material in world after water. However, concrete could be damaged under aggressive environments and many structures require repair frequent maintenance. Readymade mortars with without synthetic fibers such as polypropylene acrylic are often mortars. The partial replacement of cement by supplementary cementitious materials use alternative natural agro...

Objectives: To evaluate the strength and durability behaviour of concrete specimens that have been reinforced with micro reinforcements made polypropylene fibers microfillers nanofillers such as alccofine nanosilica, respectively. Methods: The samples were to achieve a targeted 33 MPa. In this experiment, added mix in volume fractions 0%, 1%, 0.2%, 0.3%, 0.4%, optimum percentages (15%) nanosili...

The protection of stone cultural assets is related to the transformation surface characteristic from hydrophilic hydrophobic/superhydrophobic through application a coating. suitability coating depends not only on its capability dramatically change wettability, but also other parameters such as modification kinetics water absorption, permanence vapor diffusivity, resistance aging and low volatil...

Durability characteristics of high-performance concrete (HPC) and ultra-high performance (UHPC) are evaluated in comparison to normal strength (NSC). HPC UHPC cast using commonly available materials with no special heat treatment. Concrete resistivity, rapid chloride permeability, sorptivity, porosity, resistance migration carbonation these three types assessed. Microstructure hydration product...
