“…In [79] the effect of micro-CFs on the strain sensing ability and structural capacity of RC beams in the absence of stirrups was experimentally investigated. Three beams with 125 × 350 × 1500 mm 3 dimensions and characterized by different longitudinal reinforcement ratios were monotonically tested up to failure under four-point bending scheme.…”

In recent years, cement-based smart composites (CSCs) doped with conductive filler have attracted increasing research interest because of their high potentiality as self-sensing materials for civil Structural Health Monitoring (SHM) applications. Nevertheless, several issues are still open and need further studies. This paper presents an extensive state-of-the-art in which investigations on CSCs are summarized and critically revised, with the primary aim of outlining the main limits and development points. The literature review first addresses in detail several specific issues related to fabrication and operation as sensing elements of CSC samples. State-of-the-art applications of CSCs to SHM of reduced-, medium- and full-scale structural prototypes are extensively reviewed afterwards, resulting in a database useful to critically revise the main trends and open issues of the research in this field.

“…The elastic constant of material i.e., young's modulus/modulus of elasticity (E) was decreased with increase in PE material. As the percentage of PE was increased from 0-15%, its E was reduced by 75% [5,11,14,20,23 ]. The density of PE-FA concrete was decreased when recycled PE was increased.…”

In the present paper two different plastic materials High Density Polyethylene (HDPE) and Polypropylene (PP) was replaced with fine aggregate (FA) till 10% by 2.5% increment. Different test such as compressive strength (3, 7, 28 & 60 days) (150x150x150mm), flexural strength (3, 7, 28 & 60 days) (100x100x500mm), acid attack (28, 56 & 90 days)(100x100x100mm), sulphate attack (28, 56 & 90 days)(100x100x100mm), thermal conductivity (180mm dia x 20mm thick). The compressive strength of 40.52MPa and 38.41Mpa for PP and HDPE material was observed in M30 grade concrete respectively. Similarly, for M40 grade concrete 43.6MPa and 41.8MPa for PP and HDPE material respectively. The optimum percentage of 5% and 7.5 for PP and HDPE material respectively can be replaced in concrete for flexural strength for both M30 and M40 grade. The least percentage loss in acid attack was observed at 28 days for both HDPE and PP material but for 56days and 90 days the percentage loss of weight was significantly less (< 5%). The sulphate attack for both M30 and M40 grade concrete showed less than 10% percentage loss in weight till 90 days. Thermal conductivity (k) was also reduced by 30–35% for both HDPE and PP material till 10% replacement in concrete for M30 and M40 grade.

The aim of the present paper is to incorporate two different waste plastic materials that is High-Density Polyethylene (HDPE) and Poly-Propylene (PP), were replaced with Fine Aggregate (FA) at a 10% by 2.5% increment. The widespread formation of HDPE and PP waste plastics has become a major environmental issue, endangering ecosystems and human health. Traditional disposal techniques, such as landfills and incineration, lead to pollution and resource depletion. Incorporating these polymers into concrete provides a long-term solution that reduces environmental effect while improving material qualities. The Different tests conducted are compressive strength (3, 7, 28 and 60 days) (150 × 150x150 mm), flexural strength (3, 7, 28 and 60 days) (100 × 100x500 mm), acid attack (28, 56 and 90 days) (100 × 100x100 mm), sulphate attack (28, 56 and 90 days) (100 × 100x100 mm), and thermal conductivity (180 mm dia x 20 mm thick). The compressive strengths of 40.52 MPa and 38.41 MPa for PP and HDPE material were observed in M30-grade concrete, respectively. Similarly, for M40-grade concrete, 43.6 MPa and 41.8 MPa are for PP and HDPE material, respectively. The optimum percentages of 5% and 7.5 for PP and HDPE material, respectively, can be replaced in concrete for flexural strength in both M30 and M40 grades. The least percentage loss in acid attack was observed at 28 days for both HDPE and PP material, but for 56 days and 90 days, the percentage loss of weight was significantly less (< 5%). The sulphate attack for both M30 and M40 grade concrete showed less than 10% percentage loss in weight after 90 days. Thermal conductivity (k) was also reduced by 30–35% for both HDPE and PP material, with 10% replacement in concrete for M30 and M40 grades. The use of Waste HDPE and PP material can be used to improve the mechanical, durability & thermal property of M30 and M40 grade concrete under controlled conditions.
