This paper presents the production of LC 3 concrete based on local OPC, limestone and calcined clay materials and conducts experimental investigation on the bond-slip behavior of steel rebar embedded in the concrete. The test program investigates the failure modes and bond stress-slip curve behavior of the rebar–concrete interface.

Limestone is a soft, porous rock that has similar properties to marble and other light-colored stones. The porous nature of limestone makes it an ideal material for gluing. Glue designed for use with limestone or similar stones creates an incredibly hard bond that is difficult to break, so you can glue even very large pieces together.

cumulative model of the corroded limestone is proposed and then implemented in the BPM (with parallel bond) to form the PCC model. The PCC model is applied for DEM simulations to investigate chemical effects on crack initiation, propagation, coalescence, and the mechanical properties of the limestone containing pre-existing flaws.

Limestone is a popular building material in the construction industry. It is durable and keeps calcite crystals. Quarries make limestone easy to get, so it is common in masonry projects. Ashlar masonry often uses squared limestone blocks. These are rectangular and cut with saws or chisels. Quality matters; no cracks or weathering.
