Behavior and properties of tin slag polyester polymer concrete confined with FRP composites under compression

Abstract

Polymer concrete (PC) has acquired niche in construction industry due to superior mechanical properties, recyclability and adoption of variety of aggregates. This workpresents compressive behavior and properties of one such novel PC i.e. tin slag/polyester polymer concrete. Comparable siliceous content of tin slag was considered promising to provide better mechanical strength as in natural aggregates. Cylindrical short column specimens were fabricated to be tested under quasi-isostatic loading rate of 1 mm/min. Three different aggregate sizes in gap-graded configuration were tested to assess influence on mechanical properties. In addition, specimens were confined with GFRP and CFRP to determine and compare mechanical behavior with Portland Cement Concrete (PCC). Coarsest size (4+2 mm) aggregate offered the highest strength of 37.71 MPa for unconfined sample. This performance of coarsest size persisted in confined condition with compressive strength increment of 69.68 MPa (84.7%) and 98.36 MPa (160.8%) for one and two layers GFRP; 86 MPa (128.05%) and 125.07 MPa (231.66)% for one and two-layer CFRP, respectively. It was concluded that both increment in aggregate size and number of layers improved the compressive strength.

A Review on Tin Slag Polymer Concrete as Green Structural Material for Sustainable Future

“…Based on the study from Faidzal et al (2018), two main conclusions are accepted, which are finer size tin slag aggregate and 70:30 aggregate-resin mixture ratio will result in highest strength TSPC. Then, Shakil and Hassan (2020) have performed a further study in TSPC by introducing two main approaches but still based on Faidzal study as reference. First is to formulate gap graded using tin slag aggregates with mixture of coarse and fine size particles.…”

“…In Shakil and Hassan (2020) study, the researcher has performed an experiment to analyze the compression behavior of TSPC under one and two-layer glass fiber reinforced polymer (GFRP) and carbon fiber-reinforced polymer (GFRP) confinement. Upon compressive test on unconfined TSPC specimen, the highest strength is specimen with 4 mm + 2 mm tin slag particle size with 37.71 MPa.…”

“…After the study by Shakil, Hassan et al (2020) have reported another study regarding compressive behavior of TSPC confined with CFRP. In the study, Hassan has used the optimum specification for TSPC specimen from previous studies by Faidzal and Shakil to further investigate the potential of TSPC specimen as a structural material.…”

Mechanical Properties of Tin Slag Mortar

“…Very few studies have been conducted on the use of TS as a fine aggregate replacement. Shakil and Hassan [12] evaluated the properties of TS polyester polymer concrete. The compressive strength test showed that samples attained a strength of 125.07 MPa.…”

Effect of experimental wet and dry cycles on bamboo fibre reinforced acrylic polymer modified cement composites

“…While in another quarter, polymer chemical admixtures was utilised effectively to modify the cement composites with enhanced properties observed after some tests were performed [7]. Cement mortars modified with polymers tend to have improved adhesion between fibers and matrix coupled with reduced per- meability because of low porosity [8,9]. Such modified systems possess improved flexibility and crack-bridging potential because of their low elastic modulus [10].…”
