“…The development of CPB production innovation must include quality improvements, especially in compressive strength performance. Production methods continue to develop from simple manual methods to automatic machines; therefore, material inspection is required to ensure optimal strength [16,17]. Similar to concrete mixtures in general, the compressive strength of CPB is influenced by water, clay, and aggregate content.…”

This research aims to evaluate the block method against the cube test method using variations in thickness. Paving blocks can be produced using a hydraulic machine or a simple press, and their performance can be measured based on density and compressive strength tests. The block test method shows that with the same material composition forming the paving block, a paving block with a higher thickness can lead to a lower compressive strength value. In contrast, the cube test method shows different results. The paving blocks used in this study had width and length sizes of 100 and 200 mm, respectively, and had varying heights of 60, 80, and 100 mm. The results reveal that the compressive strength of concrete paving blocks is more precise based on density. Furthermore, the empirical equation and conversion coefficient of the compressive strength of the block test to the cube test have been obtained. This empirical equation is highly recommended for the road pavement industry in controlling the quality of compressive strength, even when using block tests. Further research can help develop a formula for using additive materials in paving blocks. Doi: 10.28991/CEJ-2023-09-11-03 Full Text: PDF

“…This decreases industrial demand for OPC, lowering the expense of producing concrete and mitigating the negative impacts of CO 2 discharges during the OPC production process [ 28 ]. Given RHA’s advantageous characteristics as an SCM, its use is not limited to cementitious concrete, but may also include geopolymer concrete, self-compacting concrete, fiber-reinforced concrete, pavement blocks, bricks, and high-performance nanocomposites [ 55 , 56 , 57 , 58 , 59 , 60 , 61 ].…”

Mapping Research Knowledge on Rice Husk Ash Application in Concrete: A Scientometric Review

2022

View full text Add to dashboard Cite

This study aimed to carry out a scientometric review of rice husk ash (RHA) concrete to assess the various aspects of the literature. Conventional review studies have limitations in terms of their capacity to connect disparate portions of the literature in a comprehensive and accurate manner. Science mapping, co-occurrence, and co-citation are a few of the most difficult phases of advanced research. The sources with the most articles, co-occurrences of keywords, the most prolific authors in terms of publications and citations, and areas actively involved in RHA concrete research are identified during the analysis. The Scopus database was used to extract bibliometric data for 917 publications that were then analyzed using the VOSviewer (version: 1.6.17) application. This study will benefit academics in establishing joint ventures and sharing innovative ideas and strategies because of the statistical and graphical representation of contributing authors and countries.

“…Considering the amount of rice production, efficient utilization of waste RHA is required. The characteristics of waste RHA is very promising: it has unusually high in amorphous silica [8,22,23], a large external surface area [22,24]. Waste RHA is lightweight and has a highly porous nature [22,24].…”
