“…(4) Absolute volume change Helium pycnometer is specifically designed to measure the absolute volume of solid or liquid materials by employing Achimedes' principle of fluid (gas) displacement and Boyle's law of gas expansion. It has been widely used in many research fields such as food (Mateus et al 2007), phytology (Hill and Ormondroyd 2004), materials (Ayral et al 1992;Ramírez-Arreola et al 2015) and so on. Moreover, the testing process is in-situ, continuously and non-destructive.…”

This study evaluates the influence of aluminum sulfate (AS) on hydration and properties of cement pastes. The hydration behavior of cement paste contributed by AS was identified via isothermal calorimetry, X-ray diffraction (XRD), scanning electron microscope (SEM) and helium pycnometry. Setting time, compressive strength and pore structure of accelerated cement paste were also evaluated. Results indicate that the addition of AS can reduce setting time significantly and increase compressive strength of cement paste. Moreover, hydration process of accelerated cement paste can be divided into four stages according to absolute volume change measured by helium pycnometry, which are dissolution-crystallization stage, induction stage, rapid shrinkage stage and structure compacting stage. More nano-scale pores (pore diameter smaller than 10 nm) are generated in structure compacting stage, resulting in the "fake" absolute volume expansion. The rebound rate of shotcrete can be reduced with the increase of AS.

“…Moreover, HDPE can withstand higher temperatures than other polymers, which is essential for some applications. The foams based on HDPE inherit these properties and hence, these materials are very interesting for a wide range of applications, from structural foams [8][9][10] to fillers for lighting cement mortars [11].…”

“…number of material properties. In the last past decades, several studies have been worldwide devoted to the development of waste materials in the composition of concretes [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] to build up composite materials which could lead to the design of innovative concretes with better performances and environmental sustainability. Particular attention was accorded to the case of concrete reinforcement with PE polymer particles.…”
