Abstract Approximately 5%–7% of global Carbon Dioxide (CO 2) emissions can be
attributed to Ordinary Portland Cement (OPC), which has traditionally been used as the …

Every year, a large amount of solid waste such as fly ash and slag is generated worldwide. If
these solid wastes are used in concrete mixes to make concrete, it can effectively save …

This research studied the effect of recycled steel fibers extracted from twisted cable waste on
the fresh and hardened states of high-performance concretes. Accordingly, slump, water …

Utilizing manufactured sand (MS) with high content of stone dust, mix proportion tests were
carried to investigate the influence factors of preparing self-compacting concrete (SCC) with …

Self-compacting concrete (SCC) is a highly flowable concrete that can fill complex formwork
without the need for vibration. However, its high consistency can lead to various forms of …

This study explores the feasibility of granite waste aggregate (GWA) as a partial replacement
of natural fine aggregate (NFA) in binary blend self-compacting concrete (SCC) prepared …

In the process of pumping, the segregation of concrete mixture will lead to the difficulty of
construction, and even the possibility of pipe blocking. There is a lack of a quickly evaluation …

Self-compacting concrete (SCC) can compact itself under its weight without any external
effort and has characteristics of flowability, passing-ability, viscosity, inhibiting segregation …

One of the important problems of concrete placing is the concrete compaction, which can
affect the strength, durability and apparent quality of the hardened concrete. Therefore …

This study aims to present a joining method for precast concrete slabs in the replacement
work of the degraded concrete slab in existing steel girder bridges. The joint uses perfobond …
