Clinker has a GWP result of 897.04 kg CO2-Eq/ton. Hydraulic cement types MH, GU, and HE have GWPs ranging from 465.89 to 696.81 kg CO2-Eq/ton. Results of Cement clinker dust (CKD) is a problematic waste derived from the cement industry which may cause some problems in clinkering kiln operations and cement performance.

process converts lumps clinker to powder form. futher powdered clinker is kept in sieve shaker. powdered clinker was collected from passing 90-micron sieve. Fig.3: Clinker powder In LC3 clinker content is reduced to 50% thereby carbon dioxide emissions were reduced to 30% lower than OPC and 11% lower than PPC [4].The concrete was treated with 0.8, 1, and 1.2 of superplasticizer, and it was discovered that the concrete treated with 0.8 ml had the highest compressive strength. Overall, coarse aggregates can be partially replaced with glass waste at a weight-to-weight ratio of up to 10%, but total replacement is not achievable.Glass Waste as Coarse Aggregate Filler Replacement in Concrete

This article reviews proposed technical approaches for the manufacture and use of alternatives to Portland Cement Clinker as the main reactive binder component for ordinary concrete construction in non-specialty applications, while giving lower net global CO 2 emissions in use. A critical analysis, taking into account a wide range of technical Carbon Capture and Use (CCU) is an alternative to CCS to reuse CO 2 through chemical products. Although CCU is cheaper than CCS, no great demand for these products is present. Both alternatives have a direct impact on cement costs, which would affect economy in developing countries [13]. 5.

In this case, the B-Clay has about 70% kaolinite content based on TGA and QXRD results, making it potentially suitable to be used in cement and concrete. By contrast, the G-Clay has about 30.1% kaolinite content from TGA and 24.9% from QXRD results and therefore is not suitable for use in cement and concrete.The bulk of the cement industry's environmental burden is from the calcareous source. Calcium is mostly available naturally as limestone (CaCO 3), where almost half of the mass is eventually released as CO 2 during clinker manufacture. Iron (Fe) is the fourth most common element in the Earth's crust surpassed only by oxygen, Sustainable iron-rich cements: Raw material sources and

Concrete is a mix of several different materials: water, fine aggregates (or sand), coarse aggregates (or gravel), chemical additives, and, most importantly, cement. Cement is what binds all of these ingredients together to give concrete its durability and distinctive, grey appearance. Cement production, however, also generates most of Section snippets The hydration of OPC. The main constituents of ordinary Portland cement (OPC) clinker are the four cement clinker phases alite, belite, tricalcium aluminate and calcium aluminoferrite, referred to in the following by the abbreviated chemical formula of their composition in pure state C 3 S, C 2 S, C 3 A and C 4 AF.

Palm oil clinker (POC), a by-product of palm oil mill, can be found in large quantity in Malaysia and it is considered as waste. POC is suitable as aggregate replacement in lightweight concrete and other engineering applications due to its physical properties. This study presents the use of POC as coarse aggregate in the production of Ibrahim et al. [70] examined the compressive strength of pervious concrete (PC) produced by palm oil clinker as coarse aggregate. The PC samples were produced with 0.3 as fixed water-cement ratio. Two curing methods were selected for the palm oil clinker pervious concrete (POCPC) samples namely, air curing and water curing.The use of palm oil clinker as a sustainable ScienceDirect

However, when cementFig. 2 shows the typical heat of hydration of LC 3 observed during the first 24 h, compared with that of an OPC produced using the same clinker. In Fig. 2, LC 3 was made by partially replacing OPC with a blend of limestone and calcined clay (LC 2).The figure shows that the acceleration after the induction period is more rapid in the case of Limestone calcined clay cement and concrete: A state-of-the

The construction sector (including the manufacture of building materials) is worldwide the third-largest CO 2 emitting industrial sector. It represents 10% of all CO 2 emissions derived from human activity [11].The vast majority of these emissions come from the provision of cement (85%), of which 95% is released during its manufacture [12], Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the What is Cement Clinker? Datis Export Group

Cement industry has been always among the largest CO 2 emission sources. Almost 5–7% of global CO 2 emissions are caused by cement plants, while 900 kg CO 2 is emitted to the atmosphere for producing one ton of cement.
