Concrete contains numerous pores that allow degradation when chloride ions migrate through these paths and make contact with the steel reinforcement in a structure. Chlorides come mainly from the sea or de-icing salts. To keep the reinforcement from

The effect of a high-performance retarding additive in oil well cements was investigated under elevated temperature (165°C) and pressure (1000 psi) conditions via in situ synchrotron-based X-ray diffraction (XRD) and quasielastic neutron scattering

The purpose of this study was to develop an analytical model to predict the time required for cracking of concrete due to corrosion of the iron reinforcement. The concrete and cement specimens used for this study were batched with cover material rang

The scope of this work is designated to make use of multiple micro- and nano-additives to examine their effect collectively on fresh and hardened state of cement. Two sizes of volcanic ash, VA (6 and 17 μm), were incorporated alternatively at a cons

Early-age hydration kinetics of Portland cement with nano-additives such as nano-silica (NS) was examined using quasielastic neutron scattering (QENS). Cement pastes with different ratios of Portland cement to NS were prepared. The concentration of t

Cement paste is a disordered material whose properties and structure differ spatially and cannot be precisely predicted. We propose a new approach for developing finite element models of a hardened microstructure that accounts for the stochastic natu

Using waste agriculture and power plant byproducts to replace materials that are energy-intensive to produce can make these materials more “green”. Improved compressive strength can be obtained when rice husk ash (RHA) partially replaces ordinary

This work investigates the synergetic effect of nano-silica, NS, (up to 2% by weight) and metakaolin, MK, (up to 9.75% by weight) on the pore- and micro-structure of hardened Ordinary Portland Cement (OPC) pastes after 28 days of curing time. By addi

Concrete production contributes heavily to greenhouse gas emissions, thus a need exists for the development of durable and sustainable concrete with a lower carbon footprint. This can be achieved when cement is partially replaced with another materia
