“…Eliche-Quesada [16], evaluated the water absorption of fired clay bricks (at 900 °C) with wood ash additive, results showed an increase in initial value of absorption with 30% additive content, recording 22%, compared to reference samples with 15% water absorption percentage. Janbuala et al [47] found an identical trend in their analysis of fired clay bricks with bagasse ash additives. In fact, 30% additive content reflected a water absorption value of 24%, compared to 15% of reference samples.…”

The present work investigates the effect of using olive pomace bottom ash, the by-product of the clay brick industry, as an additive in the manufacture of fired clay bricks. Furthermore, it aims to improve the properties of clay bricks by using naturally available materials and also to develop an innovative way of recycling the waste resulting from the brick firing process. Olive pomace bottom ash was added to clay with multiple proportions (0%, 5%, 10%, 15%, and 20%) by weight. Bricks were molded by compression at 6.5 MPa, using a hydraulic brick press machine, and fired in an industrial scale furnace. The physicochemical, mineral, and geotechnical properties of raw materials were identified to study raw materials' effect on the final fired products' performance. The quality of fired specimens was determined by bulk density, linear shrinkage, water absorption, porosity, compressive strength, and thermal conductivity. In fact, samples with 5% olive pomace ash represent the highest compressive strength level, 11.5 MPa, compared to 9.65 MPa of reference samples. On the other hand, additions up to 20% increase the brick sample's porosity from 18.28% to 34% for the reference mixture and the brick incorporated with 20% of additive, respectively, and decrease the brick's bulk density from 1522 kg/m 3 to 1431 kg/m 3 for the reference mixture and the brick incorporated with 20% of additive, respectively. The incorporation of ash also improves the thermal conductivity of brick specimens. Expressly, thermal conductivity went from 0.41 W/m.K to 0.33 W/m.K for the reference mixture and the brick incorporated with 20% of additive, respectively, showing 37% of gain in thermal insulating properties of brick. Unfortunately, the capillary water absorption coefficient increases to 28% when 20% of additive is incorporated, which is not desired in the properties of construction materials. ASTMC67-07a standards: 2003, recommend water absorption level less than 17% for bricks with moderate weathering resistance. It was concluded that the addition of olive pomace bottom ash should not exceed 10% since it can be helpful in fired clay brick production based on standards requirements, leading to remarkable ecological gains without a loss of brick's performances.

“…The percentages of sugarcane leaf added on clay bricks are shown in Fig 3 . As the quantity percentage of sugarcane leaves increases, the porosity also gets increased. However, the brick weight decreases with the percentage of sugarcane leaves added [1][2][3] due to the sugarcane leaves which contain silicon dioxide as the main ingredient, which has the same properties as sand to reduce the ductility or plasticity of the soil [2]. The results of the compressive strength properties of additive sample tests are summarized in Fig 4 . As per the results, the specimen becomes more porous, which is due to the lower density and compressive strength.…”

“…The strength of a brick is due to the elements of silicon dioxide [1], which is the main component of the soil when it is fired. The disadvantage of it is the heavy weight due to the high density of the clay, which causes the problem of transportation [2]. The development of bricks by increasing the porosity along with adding the materials that are decomposed during firing, including corn cobs [1], bagasse ash [2] and rice husk ash and fly ash [3] can help to reduce the disadvantages of it.…”

This research aimed to reuse the waste of sugar cane leaves to improve the properties of clay bricks by using Design of Experiment (DOE) full factorial designs. There are 3 factors in this process, i.e., the sugarcane leaf fiber content, firing temperature and the length of sugarcane leaves fibers. The results showed that the addition of sugarcane leaf fiber content and length of sugarcane leaves fibers increased the porosity the clay bricks along with decreasing the density and compressive strength. The different temperatures did not affect the compressive strength of clay bricks. The maximum porosity values were found with the additional 7.5%wt of sugarcane leaf fiber content and 2.5 to 2.8 mm of length sugarcane leaves fibers. By adding 2.5%wt of sugarcane leaf fiber content and 1.0 to 1.3 mm of length sugarcane leaves fibers, the brick samples had the compressive strength of 19.97 MPa, which is required by ASTM C67-11 and Thai industrial standard of clay bricks TIS. 77 – 2545.
