“…Cementitious materials are widely accepted for passive fire protection because of their cost effectiveness, low thermal conductivity, and non-combustibility. Cementitious materials are also compatible and work well with different kinds of property enhancement additives or materials on both micro- and macro-structure levels, for example, carbon nanotube [ 6 , 12 ], graphene oxide [ 13 , 14 , 15 ], polymeric materials [ 16 , 17 , 18 , 19 ], phase change materials [ 20 , 21 , 22 , 23 ], fibers [ 24 , 25 , 26 , 27 , 28 , 29 ], mineral materials [ 30 , 31 , 32 ], crumb rubber [ 33 , 34 , 35 ], etc. Especially in the case of polymeric material such as superabsorbent polymer (SP), during the past decade there has been a growing interest in the application of SPs in cement-based materials [ 36 , 37 , 38 ].…”

Concrete structures, when exposed to fire or high temperatures for a certain time, could suffer partial damage or complete structural failure. Passive fire-protective coating materials are an alternative way to prevent or delay damage to concrete structures resulting from fire. Superabsorbent polymer (SP) is a synthetic material known for its ability to absorb and retain a large volume of water within itself. With this unique property, the SP exhibits great potential for use as a passive fire protection material. Although several studies have been carried out to investigate the effect of SP as a surface coating material for fire protection, very few have been investigated on the potential use of SP mixed with mortar as a passive fire-protective layer. The objective of this study is to introduce the use of SP in plastering mortar as a fire-protective layer for concrete subjected to temperatures up to 800 °C. This study is divided into two parts: (1) investigating the properties of cement mortar mixed with SP at 0.5% (CONC/SP-0.5) and 1.0% (CONC/SP-1.0) by weight of cement, and (2) investigating the potential use of SP mortar as a plastering layer for concrete subject to high temperatures. The experimental results showed that the density and compressive strength of SP mortar decreases with increasing SP dosages. From the heat exposure results, SP mortar exhibited lower strength loss due to the ability to mitigate moisture through its interconnected pore system. As for the use of SP mortar as a plastering layer, the results demonstrated the concrete specimen plastered with SP mortar had a lower temperature at the interface and core than that plastered with plain mortar. This led to a reduced strength loss of 20.5% for CONC/SP-0.5 and 17.2% for CONC/SP-1.0.

“…Compared with cracks formed by concrete, cracks in concrete with steel fibers have ductile failure modes [84,85]. Manote Sappakittipakorn et al [86] introduced short steel fibers into polymer-modified concrete (PMC) to prepare fiber-reinforced polymer-modified concrete. Regardless of the type of fiber introduced, the bending response changed significantly when the fiber was doped with PMC, from a brittle to a ductile response.…”

Polymer-modified cement-based materials have been widely used in the construction field. Acrylate lotion significantly improves durability, toughness, and bending resistance, especially durability, because the porosity of cement-based materials is reduced, preventing the entry of harmful ions and water. When acrylate lotion was at 20%, the resistance of cement-based materials to chloride ion penetration increased by 40%. At the same time, the fracture toughness of cement-based materials modified with acrylate lotion and carbon nanotubes increased by 10–15%. The flexural strength of cement-based materials modified by acrylate lotion and fiber increased by 29%. Additives such as TiO2 have a unique impact on the modification of cement-based materials, which has attracted the interest of researchers. This paper reviewed the performance of acrylate lotion-modified cement-based materials and the application of acrylate lotion in the field, which systematically increased the durability, mechanical properties, and waterproof properties of cement-based materials when acrylate lotion was modified, acrylate lotion was modified with nanomaterials, acrylate lotion was modified with other polymers, acrylate lotion was modified with fiber, and when acrylate lotion was modified with other additives. The shortcomings of acrylate lotion modification with different materials were reviewed and evaluated, and the comprehensive performance of cement-based materials modified by acrylate lotion was expected to achieve maximum strength improvement under the synergistic effect of various modifications.

“…The highest compressive strength values for bricks added with 1.5% PET before aging and for bricks added with 1.5 and 3.0% PET after aging are linked to an adequate reinforcement-matrix interaction (Figure 2), increasing bricks strength due to crack bridging effect by PET particles (Wang et al 2017;Sappakittipakorn et al 2018). On the other hand, the lower compressive strength for treatments added with 3.0% tire at 28 curing days and for both tire percentages after accelerated aging is linked to the lower bricks compaction degree (Table 5), lower density (Table 7), and higher porosity (Figure 2).…”

This research aimed to evaluate the effect of adding different polymeric waste percentages and types on the physical, mechanical, thermal and durability properties of soil-cement bricks. Tire and PET (Polyethylene Terephthalate) waste were evaluated at 1.5 and 3.0% percentages. The soil was characterized in terms of shrinkage, compaction, consistency limits, particle size and chemical analyses, whereas the waste particles were submitted to morphological characterization. The bricks were produced in an automatic press with a 90: 10 (m/m) soil: cement ratio. The soil-cement bricks were characterized by density, moisture, water absorption, loss of mass by immersion, compressive strength, thermal conductivity and microstructural analysis. PET waste stood out for its use as reinforcement in soil-cement bricks. The best performance was obtained for bricks reinforced with 1.5% PET, which showed a significant compressive strength improvement, meeting the marketing standards criteria, even after the durability test, as well as obtaining the lowest thermal conductivity values. The percentage increase from 1.5% to 3.0% fostered a significant water absorption and loss of mass increase, as well as a significant compressive strength reduction of the bricks.
