“…In one research, it is found out that up to 10% of cement can be replaced by olive biomass fl y ash, without detracting the mechanical properties of mortar (8). In another research, the results indicated that the utilization of different OW percentages in hardened blended cement pastes slightly decreases the 3, 7, and 28 days compressive strength (9). However, it is reported by some researchers that, replacing different amounts of OW instead of cement reduces the compressive strength, but increases the performance of concrete, exposed to elevated temperatures (10).…”

Reasonable and standardized use of local and waste resources is of great importance for the economic development in the world. The utilization of waste materials can result in enhanced properties and eco-friendly concrete, at the same time. In this study, it is aimed to evaluate the effect of olive waste ash on the mechanical and fracture properties of self-compacting concrete. For this purpose, self-compacting concrete mixes were prepared by the utilization of olive waste ash, in three different proportions and with two different dosages of superplasticizer. Alongside compressive and tensile strengths analysis, a series of three-point bending tests on notched beams were conducted for all mixes. Moreover, initial defects of all self-compacting mixes were evaluated by using the X-ray computed tomography method. Findings showed that using olive waste ash in self-compacting concrete mainly affects the tensile strength and fracture energy for the two different contents of superplasticizer.

“…At 56 days age, compressive strength increased by 21.5, and 25.7% for 5, and 10% replacement ratios and decreased by 20.4, and 28.9 for 15, and 20% replacement ratios, respectively. This mainly is due to the decreasing of cement amount in blended cement mixture and, consequently, decreasing the amount of calcium silicate hydrates, C-S-H, which is responsible for strength development at 7-, and 28-days age [23]. While, at later age (56 days), low replacement levels (5 and 10 wt.%) of volcanic tuffs produced satisfactory compressive strengths.…”

This study evaluates the effect of substituting cement by volcanic tuff on the workability, mechanical properties, and durability of concrete. Five mixtures were prepared with volcanic tuff ratios to cement of 0%, 5%, 10%, 15% and 20%. First, X-Ray Fluorescence (XRF) test for volcanic tuff was performed. Then, slump test was conducted for fresh concrete specimens. Moreover, tests for flexural strength, splitting tensile strength, elevated heat resistance, ultrasonic pulse velocity, and Scanning Electron Microscope (SEM) were performed at 28-days age of concrete specimens. Compressive strength, and absorption tests were conducted at 28, and 56-days ages of specimens. The study showed that slump, compressive strength, flexural strength, and splitting tensile strength were decreased with the increasing of volcanic tuff to cement replacement ratio at 28-days age. Additionally, the highest compressive strength and lowest water absorption for concrete were obtained at 56-days age of specimens and 10% volcanic tuff to cement replacement ratio.

“…Adding OWA to cement paste resulted in a decrease in its consistency, rate of initial and final setting times, compressive and flexural strengths. However, the soundness test showed that the expansion decreases with increase in OWA content [66]. -Nabil M. Al-Akhras et al, assessed the performance of OWA blended cement concrete exposed to elevated temperatures.…”

Concrete is one of the most popular construction materials in the present world. Cement is the binding material used in concrete and its production requires large quantity of natural raw materials and generates enormous volume of greenhouse gases like CO2 . In developing and under developed countries, the primary sector forms the crucial part of the economy. The management of waste generated from agricultural sector is becoming a major concern due to their negative impact on the environment. Under this scenario, several researchers have developed supplementary cementitious materials (SCMs) from these by products that can be used as a cement replacing material in concrete. Many of these materials have shown great performance and they enhanced the fresh and hardened properties of concrete. This paper is aimed at reviewing the performance of various SCMs from agricultural waste materials. Reviewing such materials helps to identify and develop new materials
