Title:Arc Thermal Metal Spraying Method for the purpose of Anti-corrosion of Steel in Hydraulic Structure

Abstract:Wastewater contains various types of microbes, including sulfur-reducing bacteria, hazardous materials (i.e., Pb, As, Sn, Cd), and acidic elements, all of which are harmful to living organism. Concrete is a porous material, which means that aggressive species of wastewater are able to diffuse into and out of it, exposing the surrounding ground to contamination.
Hazardous wastewater chemicals affect the quality of concrete and are responsible for its deterioration, as well as the deterioration of the reinforcement steel bars embedded within, after a certain period of time. Other factors that affect the quality of wastewater treatment reservoirs are ozone and activated granular carbon.  These chemicals can cause cracking, fading, and spalling of concrete during short periods of exposure.
There are many recommended methods for protecting concrete in wastewater reservoirs, including polymeric coatings and stainless-steel plating. The polymeric coating has several drawbacks, including color fading and adhesion due to direct exposure to ozone in wastewater treatment reservoir. The thermal contraction and expansion coefficients of polymers and concrete are different, which causes the detachment of the polymeric coating from concrete and can lead to spalling after a period of time.
The arc thermal spray coating process improves the life span of wastewater reservoir by using stainless steel coating rather than using its plate. To protect the wastewater reservoir from corrosion by using different metallic coatings deposited by arc thermal spraying process in pH 4 reduced by adding 0.1M sulphuric acid in distilled water.

Title:Upcycling Post-Flood Silt into Sustainable Masonry Units: Mechanical Performance and Microstructural Mechanics
Abstract: The catastrophic 2014–2015 mega-floods along Peninsular Malaysia’s east coast left massive quantities of deposited silt and debris, creating significant environmental and costly cleanup challenges. To convert this waste stream into a viable construction resource, this study investigates the chemical stabilisation of flood mud collected from Kuala Krai, Kelantan, using a biomass silica (BS) binder. Unconfined Compressive Strength (UCS) testing was conducted on untreated samples alongside specimens treated with 3%, 5%, and 10% BS binder across 3-day and 7-day curing intervals. While BS stabilisation enhanced soil strength up to tenfold (reaching 1330 kPa), mechanical performance remained below British Standards Institution (BSI) criteria for structural masonry units. To bridge this performance gap, 2% sodium chloride (cooking salt) was introduced in combination with thermal curing at 105 °C, yielding substantial UCS gains. Microstructural investigations using Field-Emission Scanning Electron Microscopy (FESEM) and Energy-Dispersive X-ray Spectrometry (EDX) revealed that the salt-heat treatment accelerated pozzolanic reactions and particle aggregation. This synergism promoted the rapid precipitation of Calcium Silicate Hydrate (CSH) and Calcium Aluminate Hydrate (CAH) gels, visible as dense, white-coloured matrices that effectively sealed soil micropores. The resulting compact microstructure satisfies the structural demands for eco-friendly, mud-based masonry units, offering a sustainable waste-to-resource solution for the construction industry.

Title: Use of Recycled Aggregate Concrete in Structural Components: recent research
Abstract: Following water, concrete is the most widely used material in the world. In a typical concrete mix, 60-70% of its volume is aggregates. Traditionally, these raw aggregates are extracted from riverbeds and aggregate banks, which has led to environmental problems. At the same time, population growth and the need for new space have led to the replacement of existing buildings in many major cities across Asia. This has resulted in a continuous stream of recycled concrete aggregate (RCA) that, if recycled and treated appropriately, can be used in the production of new Recycled Aggregate Concrete (RAC) to adopt circular economy principles in construction. This presentation shows recent work and research on RAC for structural purposes, with a particular focus the use of active confinement to improve the compressive strength of RAC. It is shown that, whilst RAC can be effectively used in structural elements, it is always necessary to understand its properties so as to ensure adequate performance.
