The ‘integral’ test method aims at the simultaneous determination of chloride migration rate and threshold content. This information is required for durability performance design reinforced concrete structures in marine environment. Standard tests are generally designed to be applied on saturated samples improve their repeatability reproducibility, but this condition differs from actual conditi...

A novel binder system for cement-based composites depending upon the strength and durability characteristics is introduced in this study. The possibility of calcined red mud cement pastes with without colloidal nano-silica (CNS) over Ordinary Portland Cement paste (OPC) at three W/B ratios (0.3, 0.4, 0.5) evaluated. optimum percentage replacement by (15%) was selected from compressive values di...

Abstract Waste glass creates serious environmental problems, mainly due to the inconsistency of waste streams. Increasing pressure reduce solid and recycle as much possible. The properties concretes containing fine aggregate were investigated in this study. purpose research was determine influence percentage optimum replacement fly ash 20% weight cement flexural strength sorptivity concrete. Th...

The cement industry is expanding rapidly around the globe, despite its significant contribution to global carbon dioxide emissions. Likewise, in Pakistan, produces million tons of and has a history contributing as high 10% country’s emissions annually. most effective technique for reducing use supplementary cementitious materials (SCMs). Limestone Calcined Clay Cement (LC3-50) recently develope...

In view of the COVID-19 pandemic, most countries in world have mandated use face masks to limit spread this dangerous disease. The billions that are produced around date generate millions tonnes plastic waste is thrown into environment. present work aims valorise single-use or surgical mortar. work, effect substituting 1–5% volume mortar with pieces 2 cm2 section and 4 explored. Mechanically, a...

An experimental study conducted to evaluate the hardened and durability characteristics of ternary blended concrete containing Nano-Silica Zeolite along with steel fibers act as micro- reinforcement has been presented in this paper. were included different dosages optimum combination above two materials (Nano-Silica -1% Zeolite- 10%) obtained through trails from viewpoint workability strength. ...

This paper emphasized the use of rice husk ash (RHA) and sugarcane bagasse (SBA) in improving concrete properties, also their combined effects on workability, compressive strength, flexural permeability water absorption capacity. Thus, this study, water-to-cement ratio was kept constant (0.45), binder materials content for conventional mix at (350 kg/m3) partial replacement cement with RHASBA u...

In this paper, perlite mining and rice production by-products, namely run-of-mine husk ash, are used as fine aggregates in combination with pumice calcareous to produce lightweight concrete. Their use is evaluated mainly terms of the durability concrete, by comparing four optimized concrete mixtures similar density strength a reference one normal weight. The sorptivity due capillary sorption, o...

In order to reduce the amount of cement required, improve workability, mechanical properties, and durability, have a positive environmental impact, supplementary cementitious materials are frequently utilized as partial replacement for in concrete mixes. this experimental investigation, effects employing waterproof supplemental such flyash, silica fume, nano along with water reduction agent wer...

Biomedical waste is a collection of medical from diverse sources that pose major risk to human, plant, or animal life now in the future. It cannot be processed discarded off without proper processing. often burnt incineration plants, yielding Incinerated Waste Ash (IBMW) which disposed landfills, are not completely leak-proof. The impact IBMW ash as cement replacement on strength and permeabili...
