Many immigrants from rural areas pour into urban areas, especially in China, and urban development faces the challenges to provide sufficient space for citizens’ acommodation, works and social contacts. So 3D development and use of land and city space become the reality with various complex buildings and constructions with modern architecture...

Estuaries and coasts can be conceptualized as connected networks of water and sediment fluxes. These dynamic geomorphic systems are governed by waves, tides, wind, and river input, and evolve according to complex nonlinear transport processes. To predict their evolution, we need to better understand the pathways that sediment takes from source...

When the corrosion expansion stress of the steel reinforcement exceeds the ultimate tensile strength of the concrete, the concrete will crack and eventually cause structural damage. Therefore, direct characterization methods of steel corrosion expansion stress can help predict the concrete cracking time, prevent corrosion expansion and repair...

Strain hardening geopolymer composites (SHGC) as a tailored group of fibre reinforced geopolymer composites are featured by large tensile strain capacity with multiple micro-cracks. This paper experimentally investigates the strain hardening behaviour of SHGC in terms of flexural stress-deflection response, failure mode and cracking, flexural...

Retarders have an important regulation effect on the hydration speed and setting time of cement. However, retarders are not conducive to the early strength development of concrete, so use early strength agents to improve their early performance. In this paper, the effects of different amounts of triethanolamine (TEA) and citric acid (CA) on the...

The deterioration of organic coatings on concrete is closely linked to the efficiency in the protection process of reinforced structures. In the present work, polyurea resin and epoxy resin, which are widely used engineering coatings, were selected to measure and compare the performance under artificial aging. Fourier Transform infrared...

Reinforcement corrosion induced by chloride ingress is one of the major threats of reinforced concrete (RC) structures exposed to chloride attack. The cracks of concrete cover provide additional paths of chloride ingress and facilitate the reinforcement corrosion. Current information regarding the influence of crack development on corrosion...

If sulfate attack on Portland cement systems has been largely investigated in the last decades, mechanisms of sulfate resistance for systems with new SCMs are still in dim, especially for the emerging materials that are limestone calcined clay cements (LC³). Using a new semi-immersion approach, we forced the penetration of sulfate ions in just...

Water absorption is an indicator of other transport properties and even durability of concrete since it provides a dominant invasion mechanism for the penetration of aggressive ions. Relationship between the water absorption and the chloride ion penetration of concrete containing fly ash, slag and silica fume at various water-to-binder ratios is...

In this paper, the influence of sodium hydroxide and water glass of various modulus, as activators, on the compressive strength, microstructure and hydration products of two alkali-activated phosphorous slag (AAPS) with different chemical composition were studied. Water glass activation shows relatively higher later compressive strength when the...

Carbonation has been proven to be a promising way to improve the mechanism properties and durability of steel slag products. CA bacteria can promote the hydration of CO2. In this study, one kind of alkali-resistant CA bacteria was chosen to investigate its effects on the carbonation process of γ-C2S. Results showed that bacteria could increase...

Alkali activated materials (AAMs) have received worldwide attention due to its lower embodied energy and environmental impact than that of traditional cementitious materials. However, the activators with high alkalinity may raise the risk of alkali silica reaction (ASR) induced deterioration when reactive aggregates are used, which thereby...

Characteristics of fly ash(FA) blended mortars (50%, 70% and 90%) at different curing ages (28 days and 180 days) under ammonium chloride solution(ACS) leaching were investigated. Mass loss under leaching, initial CaO content, Ca(OH)2 content(CH), content of chemical bonded water, and hydration degree of blended pastes were tested by XRF and DSC...
