“…They found the water absorption to be between 11.2% and 18.4%. In another study, [5] also investigated the water absorption and found the values to be between 4.1% and 4.7% for conventional concrete, but increased to between 4.5% and 12.1 when between 25% and 75% of coarse aggregate was replaced with Palm Kernel Shell (PKS) for 7, 28, and 56days age of concrete. However, [6] postulate that the water absorption of mortar can be greatly affected by the relative humidity, as samples tested at a 50% relative humidity gave water absorption results that are six time greater than those with 80% relative humidity.…”

Saw Dust Ash (SDA) is an industrial waste that has been used by many researchers in concrete to achieve economic and environmental sustainability. In this study, 5% of sand was replaced with SDA to produce concrete with different mix ratios. Scheffe's simplex theory was used for five mix ratios in a {5,2} experimental design which resulted in additional ten mix ratios. Additional fifteen mix ratios were generated from the initial fifteen, for verification and testing. Concrete cubes of 150mmX150mmX150mm were formed using the thirty concrete mix ratios generated, and soaked in water for 24hours. The water absorptions of cubes from each mix ratio were determined with the standard procedure. The results of the first fifteen water absorption values were used for the calibration of the model constant coefficients, while those from the second fifteen were used for the model verification using Scheffe's simplex lattice design. A mathematical regression model was formulated from the results, with which the water absorptions were predicted. The model was then subjected to a two-tailed t-test with 5% significance, which ascertained the model to be adequate and fit with an R2 value of 0.8244. The study also revealed that SDA can replace 5% of sand and promote environmental sustainability without significantly changing the water absorption.

“…It shows a significant influence of porosity, which was 25% and up to 40% for reference samples and those with sawdust, respectively. In their research, Md Noor et al [57] examined water absorption of concrete with palm oil kernel shells (PKS). After the research, they found that water absorption values range from 4.1% to 4.7% for the reference concrete, but increased from 4.5% to 12.1% when 25% to 75% of the coarse aggregate was replaced by PKS.…”

The aim of the research presented in the paper was to evaluate the feasibility of using hydrophobic preparations based on organosilicon compounds for protection treatment on the lightweight concrete modified with sawdust. The experimental part of the work concerns the physical and mechanical properties of lightweight concrete and the influence of two hydrophobic agents on the contact angle of the material. Lightweight concrete contact angle (θw) was determined as a time function using one measuring liquid. Water repellent coatings in lightweight concrete structure with the coarse aggregate sawdust (CASD) using electron microscopy were presented. The effectiveness of hydrophobisation of porous lightweight concretes was determined on the basis of the research. For the hydrophobic surface, the contact angle decreased and it depended on the used agents. The lowest contact angle of 40.2° (t=0) was obtained for reference concrete before hydrophobisation and 112.2° after hydrophobisation with a methyl-silicone resin based on organic solvent. The results of scientific research confirm the possibility to produce lightweight concretes modified with CASD with adequate surface protection against external moisture.

One of the innovations in concrete technology that is also in line with reducing industrial and community waste is making mask fiber concrete mixed with oil palm shells as an aggregate substitute. In this research, 10% oil palm shells were used with mask fiber added at 0.2% of the specimen volume to increase the flexural strength value of corroded concrete. Tests include corrosion acceleration tests and concrete mechanical properties such as flexural strength, density, and ductility. There are two specimens, namely pre- and post-corrosion concrete. With the acceleration process, pre-corrosion specimens are carried out on the reinforcement before the concrete molding process, while post-corrosion specimens are accelerated by corrosion after the concrete is 28 days old. Tests on pre- and post-corrosion specimens show differences in the properties and characteristics of the concrete mechanical properties test results. The flexural strength value of post-corrosion concrete tends to increase with increasing corrosion. Meanwhile, the flexural strength value of pre-corrosion concrete experienced a decreasing trend along with increasing levels of corrosion.
