Combustion and Product Characteristics of Environmentally Friendly Flame Retardant 1,1,3,3,3‐Pentafluoropropene With Three Flammable Working Fluids

Safety Science and Technology, EarlyView.
This study investigated the combustion characteristics of mixtures of the environmentally friendly flame retardant HFO‐1225zc with three combustible working fluids (HFO‐1234yf, HFC‐32, and HFO‐1243zf). The flame retardant efficacy of HFO‐1225zc on three working fluids decreases in the order: HFO‐1234yf, HFC‐32, HFO‐UFL1243zf. ABSTRACT The environmental

Mechanical, rheological, and durability performances of GGBS‐based concrete for potential application to prestressed structures

Structural Concrete, EarlyView.
Abstract Ground granulated blast‐furnace slag (GGBS) is a widely used clinker substitute in concrete, recognized for its potential to significantly reduce environmental impacts. However, its application in prestressed concrete remains limited in several countries, mainly due to concerns regarding early‐age mechanical performance and long‐term ...

Optimizing the embodied carbon of the product stage of reinforced concrete columns

Structural Concrete, EarlyView.
Abstract The construction sector faces urgent sustainability challenges. This study quantifies the potential for reducing embodied carbon in reinforced concrete columns by optimizing concrete strength and reinforcement ratios. The interplay between concrete compressive strength (20–90 MPa), reinforcement percentages (0.2%–2.0%), and embodied carbon ...
