“…The conductivity value of the six test materials shows the transfaran colour has the highest conductivity value, and the next colour black, cloudy, green, white and the lowest is blue. The difference in conductivity values indicates the influence of pigment materials added to acrylic resin during the extrusion process, namely the formation of coloured acrylic leaflets and the ratio of pigment and acrylic resin and the type of colour pigment added (Erofeev et al, 2023). The effects of pigment additives and the concentration added on the formation of coloured sheet acrylic resin.…”

In many applications, colored acrylic sheets require information on thermal conductivity values. However, thermal conductivity data has not been found in the literature and research publications, especially colored acrylic sheets. The purpose of this study was to investigate the heat conductivity value of colored acrylic sheets including transparent, cloudy, white, black, green and blue colors found in the market. This research was done with the experimental method of measuring the thermal conductivity of colored acrylic in a closed room four rectangles 80 cm x 40 cm x 40cm of 9 mm plywood coated with black paper and divided into two compartments and test material 40 cm x 40 cm x 0.3cm as patisi room. The heat source used is a 75watt incandescent lamp placed on one side of the room. Acrylic thermal conductivity is calculated based on temperature data at each measurement point reaching a steady state which is obtained at the 30th minute and taking into account the convection heat and air radiation in the test chamber. The results showed that pigment additives greatly affect the thermal conductivity value of acrylic and its value is lower than the conductivity value of acrylic colorless sheet transfaran.

In harsh or corrosive environments, waterproofing is essential for ground-contact structures. Protecting underground structures against groundwater contamination and moisture by waterproofing the base material, usually solid concrete, is beneficial. Long-term insulation system performance depends on component integrity and base material interaction. This study uses a hydraulically modified binder and finely ground construction waste fillers. Optimizing sealant and restoration is the goal. Additionally, this study will explore the characteristics and establish a systematic approach for determining the appropriate waterproofing system composition. The study measures the physical force required to remove the insulating layer in order to assess the adhesive strength of the sealant coating. This paper explains the theoretical conditions that improve the adhesion of the base- sealant sealing layer. A conceptual framework explains the relationship between sealant material adhesive strength, modified binder composition, and base surface moisture content. Empirical testing has proven this model works. A comprehensive study examined how base surface roughness and cracks affect sealant coating performance. We know the ideal strength factors. This study uses global optimization to examine optimized parameters' roles. This study analyzed experimental data statistically and analytically. According to computational analysis and experimental validation, the sealant material has an adhesive strength of 3.8 MPa and a sealant layer strength of 36–37 MPa. This product requires 3.9% acrylic resin, 80 kg/m3 finely broken concrete debris, and 0.38–0.39% plasticizer. For these components, a base surface with 9.7% to 9.8% moisture is ideal.

Implementing waterproofing measures is highly imperative in building structures that come into touch with the ground and are subject to severe or corrosive conditions. Applying surface waterproofing to the base material, predominantly composed of dense concrete, is a highly effective approach for protecting underground structures from moisture and damage resulting from groundwater containing contaminating contaminants. The integrity of each component of the insulation system and its interaction with the base material are essential factors in ensuring its long-lasting performance. This study aims to improve the compositions of concrete or brick structures that come into touch with the ground by employing a hydraulically modified binder and finely ground construction waste fillers. This optimization is intended to boost waterproofing and repair capabilities. Furthermore, this study aims to examine the characteristics and develop a systematic approach for determining the suitable composition for a waterproofing system of this nature. The study focuses on a methodology for evaluating the adhesive strength of a waterproofing coating by measuring the physical force necessary to remove the insulating layer. This paper elucidates the theoretical prerequisites that enhance the adhesive adhesion between the base and the waterproof sealing layer. A conceptual framework has been developed to explain the correlation between the adhesive strength of the waterproofing material, the modified binder's composition, and the base surface's moisture content. The efficacy of this model has been validated by empirical testing. A comprehensive assessment has been undertaken to examine the impact of base surface roughness and crack presence on the efficacy of the waterproofing coating. The values of the factors delineating the optimal strength characteristics have been definitively established. This study investigates the roles of the optimized parameters through the application of global optimization techniques. This study employed statistical and analytical approaches to analyze the experimental data. Based on the results obtained from both computational analysis and experimental validation, the composition of the waterproofing material has been determined to possess an adhesive strength of 3.8 MPa and a waterproofing layer strength ranging from 36 to 37 MPa. The primary constituents needed for this product consist of 3.9% acrylic resin, 80 kg/m3 of finely crushed concrete debris, and a plasticizer ranging from 0.38 to 0.39%. It is recommended that these components be put onto a base surface that possesses an ideal moisture content ranging from 9.7–9.8%.
