Properties of crumb rubber hollow concrete block
Journal of Cleaner Production, 2012Abstract Several researches have been conducted to determine the fresh and hardened properties of crumb rubber concrete (CRC), concrete containing crumb rubber as partial replacement to fine aggregate. The benefits of outlined from these works include low density, good thermal resistivity, better sound absorption, increase slump values and toughness,

Prestressed concrete hollow-block masonry
Building Science, 1973Abstract This paper deals with prestressed hollow-block bearing walls. A linear analysis, consisting in finding the Airy Stress Function is presented. On the basis of the numerical solution of a sufficient number of particular cases, design information is offered in the forms of easily applicable graphs.

A microwave system for measuring moisture of hollow concrete blocks
Sensors and Actuators A: Physical, 2021Abstract In this paper, the authors aim to present a microwave system for measuring moisture of hollow concrete blocks. The idea is to use this system as a new technique for Structural Health Monitoring (SHM). The hollow concrete block is an element widely used in civil construction. For that, five samples of blocks were selected and analyzed.

Using recycled concrete aggregates in precast concrete hollow blocks
Materialwissenschaft und Werkstofftechnik, 2012AbstractAmong the construction waste that could be recycled, we can mention the aggregates resulting from crushed concrete. While the acquired knowledge about the use of recycled aggregates in new concrete mixes is fairly large, the use of such aggregates in the production of concrete blocks is very limited. This research aims to study the influence of

Experimental investigation on tensile strength of hollow concrete blocks
Materials and Structures, 2021In this paper, an experimental and statistical analysis was carried out from hollow concrete blocks. Firstly, 30 blocks were tested under compression force (vertical-direction). After, 60 blocks were studied under the splitting test from ASTM–C–1006 and, later a direct tensile test was applied to other 60 blocks. The blocks, in the direct tensile test,

Research of Recycled Bearing Concrete Hollow Block
Civil Engineering and Urban Planning 2012, 2012On the premise of using stone chips, the paper studies the effect of the replacement level of recycled aggregates and w/c on the compressible properties of recycled concrete hollow blocks, then find out the linear relationship between the ratio of L K R R / ( K R : the compressive strength of recycled concrete hollow block; L R :the compressive ...
