“…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.

“…The failure of concrete in general, and of cement in particular, is an undesirable phenomenon for several different reasons, the most obvious of this being the potential effect on impact loading. Experiments such as the explosive test [ 3 ], the projectile impact test [ 4 ], the drop-weight impact test [ 5 ], and the split Hopkinson pressure bar test [ 6 ] have been created to ascertain the dynamic mechanical properties of materials. Among these tests, the Charpy pendulum impact test is most commonly used to evaluate the toughness of the energy absorption capacity of materials [ 7 ].…”

The present study deals with tests on the energy absorption capacity and compressive strength of styrene–butadiene rubber (SBR) latex-modified cementitious materials. Different polymer–cement ratios (P/C) of 0, 5, 10, 15, and 20% were carried out with the Charpy impact test at 7, 14, and 28 days of curing. The observations showed an increase in the energy absorption capacity of the SBR latex-modified cement paste in correspondence with the increase in curing times, as well as the increase in the P/C ratios. The P/C ratio of 10% was the optimal ratio for observing the highest energy absorption capacity of the SBR latex-modified cement paste, with a 43% increase observed. In addition, a linear relationship between compressive strength and the energy absorption capacity at 28 days was proposed. Based on that, the energy absorption capacity of SBR latex-modified cement paste can be analyzed or predicted by the compressive strength results, regardless of the P/C ratios. Finally, the two-parameter Weibull distribution was proved to fit by the observation data from the Charpy impact test.
