Abstract:

Strategic blending of supplementary cementitious materials (SCMs) into ordinary portland cement (OPC) helps reduce energy use and greenhouse gas emissions from concrete production. Expanding thermodynamic databases to include new reaction products from blended cements improves computational approaches used to understand the impact of blending SCMs with cement. Determination of thermodynamic parameters of cement reaction products based on temperature-dependent solubility is widely used in cement research; however, assumptions, limitations, and potential errors due to intercorrelation of the the

Abstract:

The production of cement is a carbon dioxide-intensive process. Replacing ordinary Portland cement (OPC) with industrial by-products can bring down the carbon footprint associated with cement production. Various industrial residues are currently used as alternative cementitious materials in this regard. However, developing a low carbon dioxide composite cement with different pozzolans alters the packing density, which influences its properties. Although studies have been conducted on the use of fly ash and slag at lower cement replacement levels, studies on the packing density and strength of

This chapter tells the story of Portland cement, from its invention in the 19th century until its present-day hegemony as the number one manufactured mineral product. The success story of Portland cement is rooted in the unique combination of the abundance of its raw materials, the reactivity of the high-temperature clinker product toward water, and the properties of the calcium silicate and aluminate hydration products. Further development of Portland cements today mainly addresses the formidable challenge of reducing process CO2 emissions. Options include partial replacement of clinker by lo

Abstract:

With the increase of cement output, the demand for cement expansion agents increases, and composite expansion agents have become the development trend. The purpose of this study is to study the microscopic change process and expansion effect of calcium oxide and magnesium oxide double expansion agents. After calcination at different temperatures, the change process of microscopic morphology of calcined products was observed. Through calcining dolomite at 900 °C, the mixture D900 of calcium oxide and magnesium oxide was obtained. To prepare mixed cement, 10 wt %, 20 wt %, and 30 wt % of D900 we

Abstract:

The cement industry consumes large amounts of energy to produce products, which also implies emissions, which can be partially mitigated with rational and efficient use. Products or mixtures with cement are widely used in the construction industry and for the elaboration of various structural elements, masonry, and coatings. The reaction process between cement and sand is well known and cement has been considered to produce maximum compressive strength of the mixtures where it is used due to the crystallization process. Cement-sand mixtures were made to which nopal extract was dosed, subsequen

Abstract:

With the development of prefabricated buildings, complex-shaped cement products, represented by heating-type elevated floors, have appeared on the market. These cement products can only be produced by the pouring method, with low efficiency and poor precision. Among the existing processing methods for preparing cement products, compression dewatering offers the greatest ability to produce cement products with complex shapes. However, the pressed mixing material comprises a plastic fresh mortar, which inherently lacks fluidity, making it difficult to completely fill the cavity of the shaped mol

Abstract:

The world production of cement has greatly increased in the past 10 years. This trend is the most significant factor affecting technological development and the updating of manufacturing facilities in the cement industry. Existing technology for the production of cement clinker is ecologically damaging; it consumes much energy and natural resources and also emits pollutants. A new approach to the production of blended or high-volume mineral additive (HVMA) cement helps to improve its ecological compatibility. HVMA cement technology is based on the intergrinding of portland cement clinker, gyps

This paper investigates the sulfate resistance of blended cements produced by replacing 10, 20, and 30% of sulfate resisting cement (SRC) with Algerian natural pozzolan. Ordinary and blended cement mortar specimens were cast and immersed in a 5% sodium sulfate solution for 3 years. The sulfate resistance of mortars was evaluated by visual examination, compressive strength, mass change and diffraction (XRD), which was used to identify the degradation products formed by sulfate attack.The test results demonstrated that the sulfate resisting cement incorporating 10% of natural pozzolan was less s

Abstract:

The utilization of supplementary cementitious material [SCMs] as a partial substitution of cement is one of the most effective way to lower carbon-dioxide emissions in the cement production. Although previous research on the use of sugarcane bagasse ash [SBA] and limestone as SCMs as a partial substitution of cement has been reported. However, there is little research on their combined use in cement. The impact of SBA and limestone on the hardening and hydration property in blended cements were examined by testing properties of fresh and hardened mortars supplemented with TGA and XRD analysis.

Physico-chemical processes of hardening of a cement stone are accompanied with shrinkage is known to result in crack formation, loss of concrete structure integrity and finally, to shorter service life. These drawbacks make problems in using traditional portland cement based mortars for joint grouting and crack repair in concretes. Known-in-the-art solutions based on calcium aluminate cements are also not efficient due to high cost and instability of cement stone hydration products over time in various service conditions. Shrinkage-compensating alkali activated slag cement mortars are proposed

The mechanical strength change trend of Portland cement at different temperatures (+5°C, 0°C,-5°C,-10°C) was researched, and hydration performance and slurry structure of Portland cement was studied. Results showed that hydration process of Portland cement didn't vary with the lowering of curing temperature, but each stage of hydration time extended. The temperature decrease prolonged formation time of hydration products, making the early microstructure to loose, produces more pores, and causes the early mechanical strength of Portland cement to decrease.

Even if cement is a well-consolidated material, the chemistry of cement (and the chemistry inside cement) remains very complex and still non-obvious. What is sure is that the hydration mechanism plays a pivotal role in the development of cements with specific final chemical compositions, mechanical properties, and porosities. This document provides a survey of the chemistry behind such inorganic material.

Abstract:

Portland cement production is an energy-intensive process that releases carbon dioxide into the atmosphere. To reach carbon neutrality by 2050, it would be necessary to implement innovative measures in the cement industry to deliver carbon neutrality. In this respect, it is striking that the new cement types made with high contents of industrial by-products will act as a lever to combat climate change. Accordingly, the purpose of this study is to assess coal–ash blended cements in light of climate change mitigation. In particular, ground coal bottom ash could be considered as a novel constitue
