Study on microstructure and bond strength of interfacial transition zone between cement paste and high-performance lightweight aggregates prepared from ferrochromium slag

•High-performance lightweight aggregates (HPLWA) are successfully fabricated by using ferrochromium slag, fly ash and bauxite as raw materials.•The high-belite sulphoaluminate clinker is prepared and coated on the surface of HPLWA by one-step sintering technique to obtain an outstanding surface reac...
