“…Also, they reported that the setting shrinkage can be reduced to an almost negligible level by incorporating a shrinkage-reducing agent. Also, Yeon et al (2014) observed that the setting shrinkage of acrylic polymer concrete fell between 29.6 and 39.6×10 −4 and the magnitude increased as the MAA content increased because an increase in MAA content promotes the setting reactions.…”

This study evaluated the setting shrinkage characteristics of Methyl Methacrylate (MMA)-modified vinyl ester polymer concrete with different curing ages, MMA contents and curing temperatures. Results have shown that most of the setting shrinkage developed within 24 h after curing initiation. It was also found that an increase in MMA content led to an almost linear decrease in setting shrinkage, indicating that adding an MMA monomer was an effective measure to reduce the setting shrinkage of MMA-modified vinyl ester polymer concrete. A higher curing temperature tended to result in greater setting shrinkage, indicating that low-temperature curing is beneficial for reducing the setting shrinkage. The magnitude of setting shrinkage observed in vinyl ester polymer concrete was much greater than the drying shrinkage typically observed in ordinary Portland cement concrete but was smaller than the setting shrinkage of polymer concrete incorporating other types of binder.

“…Inspired by natural bio-composites, such as nacre, which is composed of 99 vol% hard and brittle aragonite (CaCO 3 ) layers separated by 1 vol% soft protein layers, which are 1000 times as tough as its constituent CaCO 3 phase, the strategy of introducing soft substances into the hydration system to hybridize the hydrates was proposed to improve the strength and toughness of inorganic cementitious materials. The introduction of organic molecules or polymers into the inorganic matrix has drawn considerable attention in recent years [ 7 , 8 , 9 ]. Polymers-modified inorganic materials can fill the pore defects, bridge the fine cracks, and generate an interpenetrating network with cement hydrates, hence improving the toughness [ 10 ].…”

In this work, two series of chemically reactive polymers, silane coupling agents (SCAs) and water-soluble polymers, were specifically designed as an additive to improve the ductility of slag geopolymer paste by vibration pressure technique. The influences of organic polymers on the fluidity, rheological behavior, mechanical property, porosity, and toughening mechanism of slag geopolymer were investigated. The polycondensation and bonding characteristics of organic–inorganic products were calculated by 1H liquid nuclear magnetic resonance (NMR) technology and Fourier transform infrared (FT-IR). The polymerization degree of composite geopolymer was evaluated by 29Si NMR and X-ray photoelectron spectroscopy (XPS). The microscopic morphology of the geopolymer matrix was analyzed using scanning electron microscopy (SEM). The results showed that the dosage of the KH570 and PAA-Na with 5 wt% behaved best in improving the flexural strength and the compressive strength of geopolymer in their corresponding organic series, respectively. The addition of polymers decreased the fluidity and the fluidity loss ratio of geopolymer slurry but reduced the harmful pores of hardened geopolymer. The organic polymers acting as bridge-fixed water molecules weakened the repulsion force, and formed a three-dimensional network through molecular interweaving in a geopolymer matrix. Methacryloxy in silane coupling agents and carboxyl group in water-soluble polymers may contribute to the improvement of hydration product structure through strong bonding with C-A-S-H. Microscopic measurements indicated that the addition of KH570 and PAA-Na in geopolymer could form 73.55% and 72.48% Si-O-Si with C-A-S-H gel, higher than the reference, and increase the polycondensation degree of C-A-S-H phase, reflected by the increased generation of Q2 and Q2(1Al) and the longer chain length, leading to a higher densified geopolymer matrix with high ductility.

“…On the other hand, acrylic polymers have been extensively used in coating (Kim et al , 2018; Sebastian and Axel Mu1ler, 1999) and adhesive industries (Dhole et al , 2017; Silvestri et al , 2009). These materials have good resistance to ultraviolet light (Nguyen et al , 2018), hydrolysis (Morita et al , 2015), oxidation (Arekhi and Jamshidi, 2018) and fast drying of the films (Cools et al , 2018; Yeon et al , 2014). Considering the wide use of acrylate polymers in the paint and coating industries, poly (methyl methacrylate) (PMMA) is an important acrylic polymer (Ito et al , 2018; Dai et al , 2018) because it has adequate properties (Tsai et al , 2010; Araújo et al , 2018) and especially low cost (Sirapanichart et al , 2011).…”

Purpose This paper aims to improve some properties of poly (methyl methacrylate) by copolymerization with butyl acrylate (BA) monomer along with the incorporation of the stable and economical synthesized silicone-containing monomer hexamethyldisilazanomethacryloxyphenyl ketone (HDMK) into the copolymer matrix. Design/methodology/approach For this target solution copolymerization of methyl methacrylate (MMA), BA and HDMK were carried out using a 250 mL four-necked round-bottom flask. Before solution polymerization start-up, the reaction vessel was first charged with 34.8 mL toluene and heated to 170 Â°C with stirring and reflux cooling. A monomer mixture of 25.86 g (260 mmol) MMA, 26.40 g (200 mmol) BA, 3.00 g (8.60 mmol) HDMK and 0.45 g (2.00 mmol) dibenzoyl peroxide was added continuously from the dropping funnel over a period of 4 h. Findings The HDMK was successfully synthesized and the water resistance of acrylic resins was improved because of the existence of HDMK. Research limitations/implications The materials that were used in this research paper had a reasonably low cost. Also, the procedures for synthesis of monomers and polymers were extremely easy because there was no need for high pressure or temperature and no dangerous solvents were used. Practical implications The acrylic resin that contained HDMK was used to synthesis a white architectural paint for exterior coating. Examining the paint characteristics has shown acceptable washing and abrasion resistance, good brushing, excellent storage stability and great surface coating. Originality/value HDMK was synthesized for the first time.
