...Samiha Tasneem; Mohammad Inqiyad Chowdhury; Rabiah Mahjabeen; Sk. Rakibul Islam Purpose This study aims to explore the durability of fibrous concrete enhanced with natural, synthetic and hybrid fibers combined with supplementary cementitious materials (SCMs). The primary goal is to evaluate...

... as this study aims to enhance the performance, durability and sustainability of shotcrete used in lining of tunnels. Design/methodology/approach An experimental investigation was conducted wherein shotcrete mixes were prepared by adding various dosages of GNPs by weight of cement to the mixes varying from...

... durability compared to the reference sample without additives. However, excessive proportions of BP (>60%) or CP led to exceptions in this trend An exception to this trend was observed when BP was added in proportions exceeding 60% or when CP, indicating potential limitations in some additive formulations...

...Sandeep Sathe; Shahbaz Dandin; Makrand Wagale; Pankaj R. Mali Purpose This study aims to investigate and compare the influence of various fiber types (polypropylene, steel and glass) on the workability, mechanical properties, ductility, impact resistance, durability and microscopic properties...

... tensile strength) were assessed through standardized tests. The durability was further investigated via water absorption, acid attack, rapid chloride permeability tests, open porosity test and Sorptivity test. To gain deeper insights into the internal structure of concrete, microstructure analysis...

...Suehail Aijaz Shah; Manzoor Ahmad Tantray; Jan Mohammad Banday Purpose Durability of concrete can be enhanced by reducing the pore size/volume of pores or by entrapping the pores. This can be achieved by adding concrete admixtures that have particle size finer than cement. In this study, GNP...

...Mohammad Reza Adlparvar; Morteza Esmaeili; Mohammad Hossein Taghavi Parsa Purpose This paper aims to study the influence of the presence of steel and polyolefin (PO) fibers on the mechanical and durability properties of fiber and hybrid fiber-reinforced concrete (FRC and HFRC). Design...

...Abdelaziz Logbi; Mohamed Mani; Toufik Choungara; Abdelouahed Kriker Purpose This paper aims to study the effect of mineral additions on the mortars’ physical, mechanical and durability properties. Two local mineral additions, considered inert, are chosen: limestone fillers from North-East...

... properties and low durability of adobe blocks by incorporating date palm wastes as a natural reinforcement and lime as a stabilizer. Design/methodology/approach Soil from the region of Biskra in Algeria was mixed with sand and lime in suitable ratios. Then, date palm wastes were added to the previous...

... properties and durability of an ultra-high performance concrete from materials existing on the Algerian market. Design/methodology/approach Three mineral additions such as granulated slag, quartz powder and silica fume are incorporated into the cement with 15, 23 and 25 per cent, respectively...

... value of Sawdust briquette. Briquette quality is evaluated mainly by briquette density. Briquette density is very important from the viewpoint of manipulation, burning speed, briquette durability, etc. During our research, theoretical analyses of parameters which have an impact on briquette quality were...

...K. Salhi; B. Mezghiche This study investigates the effect of slag of blast furnace (SL) and sand of dune, (SD) replacement of cement on the durability of cement to chemical aggressive water (acid and sulfates) attack, Tow replacement levels were considered in the study: (5% sand of dune + 15% slag...
