This paper reports results from comparative testing the reaction "alkali ‒ active silica" in traditional Portland cement and alkaline Portland cement with the addition of metakaolin. The research is based on studying the process of structure formation in cements in the contact zone "cement stone – basalt". The research results allow us to conclude that the dynamics of the process of interaction of the reaction "alkali‒silica" in cements may be constructive and destructive in character.

This thesis presents the design and development of an alternative cement called ‘Alkali Pozzolan Cement’ (APC) for ‘integral sustainability’. The term ‘integral sustainability’ is a philosophical concept that implies an integration of not only the aspects related to ecological sustainability, but also those of technological, economic and social sustainability. Accordingly, this research can be considered as engineering as well as philosophical research; hence, mixed research methods were adopted to achieve the research objectives.

It has been previously established that alkali silica reaction (ASR) in concrete may be controlled by blending Portland cement with suitable hydraulic or pozzolanic materials. The controlling mechanism has been attributed to the dilution of the cement's alkali content and reduced mobility of ions in concrete's pore solution. In this project an attempt has been made to identify the factors which influence the relative importance of each mechanism in the overall suppression of the reaction by the use of blended cements.

The underlying mechanism of poor dispersibility of EVA is attributed to hydrophobic groups of polymers, a variation in the adsorption rate and molecular diffusion to the interface where they cluster together.

Abstract:
Rigid pavement is a type of pavement that uses cement as the main binding material and has a high level of stiffness. The prolonged use of cement has increasingly negative impacts on the environment. Using geopolymer as a substitute for cement can be an eco-friendly alternative solution. Geopolymer is an environmentally friendly material that can be developed as an alternative to cement concrete in the future. The purpose of this study is to determine the compressive strength of geopolymer concrete using rice husk ash and shell as fine aggregates in rigid pavement. The research method used is

Abstract:
Orphaned or abandoned sulphide tailing disposal sites pose significant environmental hazards, including eolian dispersion, water erosion, acid mine drainage, and heavy metal mobility. Phytostabilization, an eco-friendly strategy, entails the use of alkaline amendments alongside non-native plant species capable of thriving in environments with high concentrations of heavy metals. A greenhouse experiment was conducted to assess the effect of a commercial cement which contained 46.3% sand, applied alone or combined with three magnesium (Mg) reagents on the shoot dry yield (DMY) of ryegrass (Loliu

Abstract:
Abstract The kinetics of the anodic reaction has been studied in alkaline solutions and in cement mortar. Use of synthetic pore water has the advantage that environment is known and can be controlled. The anodic reactions can be studied without disturbance from the cathodic ones in deoxygenated water. Iron and steel exhibit passivation in alkaline media with a steady state passive current that is independent of potential after a days exposure. The properties of the passive film are changed by polarisation. This makes it difficult to explore the anodic kinetics. Due to the polarization induced

Abstract:
Abstract This paper describes a new probe for potential monitoring of cathodically protected structures. Features of the probe are: elimination of copper sulfate solution, elimination of interliquid potential contribution, elimination of ohmic drop contribution, reliable measurement in presence of stray currents, and high durability. The probe is composed of a steel coupon and a reference electrode, both embedded in an alkaline mortar, simulating a coating defect. Different types of internal reference electrodes were tested, like Mixed Metal Oxide (MMO) titanium activated and AISI 304 stainles

Abstract:
Cement contributes CO2 emissions to the atmosphere, which is harmful for human health. Several researchers have conducted experiments to find materials that have the potential to be used as cement substitutes. Fly ash and perlite are wastes that contain silica as well as high aluminum, so they have potential as cement replacement materials. In this study, geopolymer concrete mixtures were made using fly ash and perlite with a NaOH concentration of 10M – 16 M, a Na2SiO3/NaOH ratio of 2.5 and alkaline solution to fly ash ratio (AA/FA) of 0.5. The curing method used was using an oven at 80 °C for

Abstract Engineered glass-ceramic coatings that contain hydraulically reactive calcium silicates have been shown to be remarkably effective in increasing the bond strength between reinforcing steel and the surrounding concrete or mortar. The coatings are a mixture of portland cement and alkaline-resistant basecoat glass enamel. X-ray diffraction patterns indicate that all of the major reactive compounds, such as dicalcium silicate and tricalcium silicate and the ferrites and even gypsum survived the firing of the frit-cement mixture onto steel.

Abstract:
Abstract Oil refineries use sulfuric acid or hydrofluoric acid as a catalyst in the alkylation of isobutene. Process wastewater streams discharging from alkylation units, where this process step takes place, are often characterized by a low pH. This low pH wastewater reacts with alkaline Portland cement in concrete wastewater collection and conveyance structures, compromising their structural integrity. This paper reviews one oil refinery’s use of high-density polyethylene liners to renovate and protect its deteriorated concrete process sewer structures downstream of its sulfuric acid alkylati

Abstract:
Geopolymers (GPs) are a class of amorphous, aluminosilicate-based ceramics that cure at room temperature. GPs are formed by mixing an aluminosilicate source, which is metakaolin in this case, with an alkali activator solution, which can be either sodium or potassium water glass. GPs have attracted interest for use in structural applications over the past few decades because they have superior mechanical properties to ordinary Portland cement (OPC). Additionally, they can tolerate much higher temperatures and produce a fraction of the CO₂ compared to OPC. This project aims to develop geopolymer
