This paper dwells on the function of fly ash as a cement replacement material and pore-filling material in the concrete and the resultant effect on strength properties. The investigations revealed that the optimum percentage of substitution of fly ash for cement varies with the w/c ratio of the concrete. The higher quantities of …
The chemical characteristics of wood ash, which govern its credibility to be used as a replacement for cement, such as silica (SiO 2), alumina (Al 2 O 3), iron oxide (Fe 2 O 3) and quicklime (CaO) differ significantly from one species of trees to another.Variation in the chemical characteristics of ash produced from different species …
The potential of Orange peel ash (OPA) as a cement replacement material was investigated with focus on the effect of OPA content on the physicomechnical properties such as consistency, setting times, soundness, compressive and flexural strengths of OPA-cement blend for cement replacement between 2.5-10% at 2.5% interval. The optimal …
Research into innovative new materials that can replace or reduce the use of cement is focusing on options such as biocements that grow in a similar way to coral thanks to the action of microorganisms; …
RHA contains amorphous silicon oxide (SiO 2), or silica, and it is a highly pozzolanic material which makes it a suitable material for a partial replacement of Portland cement in concrete mixtures (Zhang et al., 1996, Sata et al., 2007, Antiohos et al., 2013, Prasittisopin and Trejo, 2015).
Cement replacement materials are special types of naturally occurring materials or industrial waste products that can be used in concrete mixes to partially replace some of the portland cement. Cement replacement materials are frequently called fine minerals or pozzolans. Surprisingly, concrete with cement replacement materials can actually be ...
cement replacement material for making structural grade concrete: An overview, Ain Shams. Engineering Journal 6 429-437 [47] Arunkumar K, Muthukannan M, Suresh K A, Chithamb ar G A 2021 Mitigation ...
Cement is the main materials for the construction and it is very expensive. Considering the growing demand of cement, the researchers are probing towards the new cement replacement materials.
This material compares favourably with fly ash and wastes from the oil palm industry. The only difference noticed is in the low content of Al 2 O 3 (4.09%) and Fe 2 O 3 (2.26%). Concrete mixes have been proportioned to have various percentages of cement replacement with sawdust ash (SDA) ranging from 0% to 30% by mass.

Cement replacement materials are necessary, including coal fly ash, ground granulated blastfurnace slag, silica fume, ground glass natural pozzolans or calcined clay (eg, …
One way to lower emissions from making cement is to reduce the amount of limestone used by mixing it with a cement-like material that does not emit CO 2. Fly ash, the powdery by-product of coal ...
The CBA as a cement replacement material in cement composites can enhance fresh and mechanical properties on concrete or mortar up to a specific ratio. The finding shows that grinding CBA from coal can be used in concrete or mortar as a substitute material in violent environments. Overall, this study suggests the concept of …
The use of pulverized BC as a cementitious materials mixture has recently gained research momentum because this usage can lock BC in inert materials and reduce cement consumption simultaneously. This paper presents a review on the use BC particles as an additive or cement replacement in cementitious composites over the last few …
So naturally, the search for alternative supplementary cementitious materials to replace Portland cement has picked up speed over the past decade. It is clear that there are a large number of potential OPC replacements and substitutes being developed by start-up companies, universities and established cement manufacturers. ...
The target is to analyze the most dominant range of w/c ratio used for concrete mixes with glass powder cement replacement. The studied articles were arranged into groups in Fig. 1. of w/c ratio ranging from 0.35 to 0.6 with an increment of 0.05.As shown in the Figure below, the most w/c ratio range used was 0.45–0.5, giving …
Cement replacement materials have been the subject of increasing levels of research and development in recent years. These products are employed for many reasons, including to modify the properties of concrete, although the most urgent need for their use currently is to produce more sustainable concrete and reduce waste. Recently, …
In this research work, wheat straw ash an agricultural waste is used as cement replacement material. The cement replacement percentages are 0%, 5%, 10%, 15% and 20%. A total 45 cubical specimens ...
The use of supplementary cementing materials (SCM), design of concrete mixtures with optimum content of cement and enhancement of concrete durability are the main issues …
Limited research has been conducted by adding biochar (as filler and cement replacement material) in cementitious composites. Gupta et al., [65] evaluated elastic modulus of mortar prepared using 1-5 wt% wood, food, and rice waste biochar. The results revealed that incorporation of 1 wt% and 2 wt% wood waste biochar increased …
Like fly-ash, ground granulated blast furnace slag was initially considered waste and disposed of in landfills. However, it was discovered that the material could be used to replace up to 80% of cement in concrete, making it one of the best alternatives to cement. Portland cement must still be added to the concrete mixture to obtain the best ...
Partial replacement of energy-consuming cement with reusable materials is among the best strategies used to achieve eco-friendly construction material. For example, cement can be replaced …
Pure-cement concrete is typically designed for 28 days since it does not exhibit further strength development beyond this point, unlike concrete with supplementary cementitious material replacement. The concrete mix design represents an actual mixture used for a thick mat foundation obtained from a previous study [10]. The initial slumps …
