“…Filled lightweight concrete is made by adding lightweight fillers directly or indirectly modified into the concrete and mold [ 12 , 13 ]. At present, fillers for lightweight concrete mainly include expanded perlite [ 14 , 15 ], foam particles (such as polystyrene foam balls [ 16 , 17 ], ceramic balls [ 18 , 19 ], and so on), and expanded clay [ 20 , 21 ]. Stefania Grzeszczyk et al [ 22 ] added expanded perlite to concrete to obtain lightweight concrete.…”

Lightweight concrete is widely used in the construction industry due to its low density and high strength. In this paper, lightweight concrete was prepared by a simple two-step method. Firstly, the light calcium carbonate reinforced epoxy macrospheres (LCR-EMS) material was obtained by adhering calcium lighter carbonate powder to the expanded polystyrene foam spheres (EPS) material using the “balling method”. In the second step, the LCR-EMS was mixed with water, cement, and the hollow glass microspheres (HGMS) material using the “molding method” to obtain lightweight concrete. The combination of macroscopic photographs and microscopic morphology shows that the LCR-EMS material itself is uniformly encapsulated and well bonded to the matrix. Test results show that the density of the lightweight concrete decreases with an increase in the volume fraction of stacked LCR-EMS, the diameter, and the proportion of HGMS in the matrix, but it decreases with a decrease in the number of layers of LCR-EMS. The compressive strength of lightweight concrete exhibits a completely opposite trend. When three layers of LCR-EMS were used as filler material, the density and compressive strength of the concrete were 1.246 g/cm3 and 8.19 MPa, respectively. The density and maximum compressive strength of lightweight concrete were 1.146 g/cm3 and 6.37 Mpa, respectively, when filled with 8–9 mm-2L-90 svol% of LCR-EMS and 40 wt% of HGMS in the matrix. Compared with lightweight concrete filled with 90% EPS, the density increased by 20% while the compressive strength increased by 300%.
