Behavioural Studies on Triple Blended Foam Concrete

Abstract

In recent days construction industry focuses on other than conventional concrete in infrastructural purposes like building etc., due to excess usage of cement, sand and other aggregates which leads depreciation of natural resources and effects on the environment. By utilization of lightweight bricks and foam concrete which reduces not only its self-weight but also improve resistance against heat and sound insulation and architectural features. The density of foam concrete varies from 300 to 1800kg/m3. Foam concrete composes of cement, water, fly ash and foaming agent without coarse aggregate. The function of foam is to create air bubbles in the cement-based slurry. The density of foam concrete depends on the quantity of foam added. The foam creates several pores with this effect; it has low thermal conductivity. As density of foam concrete is low at same time strength also low when compared to conventional concrete, so an attempt made to improve mechanical properties of foam concrete by adding admixtures like Silica fume and GGBS in different percentages. In these experimental studies, the workability and compressive strengths are mentioned

Challenges in Foamed Concrete: Exploring Alternative and Sustainable Materials – A Comprehensive Review

“…Different dosages of foamed agent (0.3%, 0.6%, and 0.9%) are investigated to stabilize bubbles (18). Other mixing approaches were studied, achieving a compressive strength of 101 MPa and 28 MPa with 1620 kg/m3 for the reference and lightweight concrete (18,59,60).…”

“…Additionally, the exploration of physic-mechanical and structural properties of alkali-activated fly ash foam concrete, incorporating Yellow River silt, likely involved an evaluation of the mixture's fluidity. Collectively, these studies shed light on various aspects of the fluidity of foam concrete, offering valuable insights into its behavior (15)(16)(17)60).…”

“…The stability of preform foam, coupled with the deliberate incorporation of microbubbles into the concrete matrix, significantly contributes to this improved thermal efficiency (14,40,61,64,107,113). However, it's crucial to note that while these advancements positively impact insulation, they also exert influences on both compressive strength and elastic modulus, underscoring the need for a balanced consideration of multiple factors in the pursuit of energyefficient construction solutions (60,104,115,116).…”

Effect of strain rates on the forming properties of DP Steel at high-temperature

“…The formability can be described in different varieties , FLD is the most precise since it shows how much sheet metal can deform before a material experiences plastic instability [6][7][8]. The initial tail symptoms of localized necking are bound to occur during the forming.The maximum and lowest strains that can be endured before a failure occur depend on the capacity of material [9][10][11][12][13][14].…”
