The finding indicates that panel concrete provides consistent insertion loss and exceed the minimum value of effective noise barrier followed by concrete hollow block and vegetation.
The study presented in this paper reveals that the added concrete, normally with higher compressive strength than the substrate concrete, may possibly have an influence on concrete-to-concrete bond strength.
The result of the laboratory test indicate a sturdy lighter-than-concrete building material with various potential uses—for ceilings, walls, wooden board substitute, or as an economical alternative concrete block.
The cost analysis suggests that slag-bond concrete blocks can be made at a lower cost compared to the commercial cement block if they are mass produced.
ACI rectangular stress-block parameters are able to predict well the strength of conventional concrete structures but their applicability for GPC is questionable.
Tests results have provided the maximum percentage of recycled aggregates that can be included in new concrete block mixes without affecting blocks compressive strength.
From the point of view of natural resources, ecology and economy, it is virtually impossible to imagine substituting concrete by any other material.
The authors conclude that their new equivalent rectangular stress block is suitable for both normal- and high-strength concrete.
This study suggests that the assumption of k3 = 0.9 in previous studies for conventional Portland concrete is not suitable for use in deriving the stress-block parameters of GPC.
