“…Main materials that emit styrene are the styrene‐butadiene rubber (SBR) and the styrene‐butadiene latex . These materials are widely used for the covering of garage flooring and parking lots to reduce the penetration of water soluble salt and repair of concrete floors . Furthermore, the SBR is one of the components of the blend used for rubber tyres and a major product in latex, for example, used in textile carpet backings.…”

The aim of this study was to identify determinants of aldehyde and volatile organic compound (VOC) indoor air concentrations in a sample of more than 140 office rooms, in the framework of the European OFFICAIR research project. A large field campaign was performed, which included (a) the air sampling of aldehydes and VOCs in 37 newly built or recently retrofitted office buildings across 8 European countries in summer and winter and (b) the collection of information on building and offices’ characteristics using checklists. Linear mixed models for repeated measurements were applied to identify the main factors affecting the measured concentrations of selected indoor air pollutants (IAPs). Several associations between aldehydes and VOCs concentrations and buildings’ structural characteristic or occupants’ activity patterns were identified. The aldehyde and VOC determinants in office buildings include building and furnishing materials, indoor climate characteristics (room temperature and relative humidity), the use of consumer products (eg, cleaning and personal care products, office equipment), as well as the presence of outdoor sources in the proximity of the buildings (ie, vehicular traffic). Results also showed that determinants of indoor air concentrations varied considerably among different type of pollutants.

“…The formation of AH 3 in this study is mainly ascribed to the hydration reaction of ye'elimite, anhydrite and water, according to Eqs. (1) and (2). Generally, the amount of AH 3 increases with hydration time prolongation, and polymer dispersion shows limit impact on it.…”

“…Polymer admixtures, especially polymer dispersions, are formulated into cement mixtures for modification of cement mortar and concrete. The key properties of polymer dispersions are their ability to form flexible and homogeneous polymer films inside of cement matrix along with the cement hydration process [2,3], which gives cement mortar and concrete well adhesion and cohesion properties [4]. The use of these dispersions in cementitious materials contributes to decrease water-to-cement ratio [5], increase strength and improve durability [6][7][8][9][10][11].…”

The influence of three polymer dispersions [styrene-butadiene copolymer (SB), styrene-acrylic ester copolymer (SA) and polyacrylic ester (PA)] on the hydration of calcium sulfoaluminate (CSA) cement within 72 h was investigated by using isothermal conduction calorimetry, X-ray diffraction analysis and thermal gravimetric analysis. The results indicate that these three polymer dispersions perform different influences on the hydration heat flow of CSA cement during different periods, they all postpone the occurrence time of the maxima peaks, and its extent is mainly dependent on the addition amount. Polymer dispersions manifest great retardation on the initial hydration of CSA cement, and the effect is much more significant within 1 h. In this stage, the generation of ettringite is strongly delayed; however, the formation of ettringite is accelerated by these polymer dispersions at and after 2 h. Among these three polymer dispersions, PA demonstrates the highest acceleration effect on the hydration degree.

“…Therefore, the development of tech-niques, which could minimize these adverse influences of such inferior properties, is very important. In the construction industries, a judicious choice to tackle or minimize the adverse influence of the above shortcomings could be achieved by the exploitation of mineral admixtures [7][8] and/or polymers [9][10]. The former, although can assist in modifications of the material microstructure, it has to be added in relatively large amounts in order to be effective.…”

“…The latter, however, can be added in small amounts in order to change the material microstructure, resulting in enchantment in the material properties [10]. In the field of construction industries, different types of the polymer have been used such as; re-dispersible polymer powders, liquid resins, monomers and water-soluble polymers [9]. Among these types, polyvinyl alcohol (PVA) has been utilized in numerous applications.…”

In this study, an experimental research was dedicated to investigate the properties of clay brick treated by polyvinyl alcohol (PVA). Two methods of treatment were conducted. The first contained treating clay brick by submerging the specimens in 1%, 2% and 3% of PVA solution, whereas the second involved coating the brick specimens with 6% PVA (i.e. a high viscous solution). The treated specimens were allowed to dry under ambient temperature in the laboratory before being tested. Standard tests employed for brick specimens were applied. Regarding the specimens treated using the submerging method, results showed that there was a significant contribution of PVA to the compressive strength, total water absorption and efflorescence tests, in which the specimens reached the best performance when PVA was increased to 3%. However, the brick specimens coated by PVA showed a slight increase in the compressive strength, but a noticeable decrease in the water absorption and efflorescence.
