Abstract
Purpose: One of the innovations needed to create lightweight wall is possible by using Styrofoam as a partially fine aggregate substitution. This study was conducted to study the flexural strength of Styrofoam lightweight concrete panel walls with a high-volume fly ash content in a square column connection. Methodology: The size of the wall panel used is 120 x 30 x 10 cm with 10 x 10 cm square column holes as support on both sides. In the centre of the wall panel, four square holes with a dimension of 18 x 4 cm were created. The variations of fine aggregate replacement with Styrofoam were 50% and 60% by the volume of fine aggregate, while the use of Fly ash is 50% as partially cement substitution. SCC (Self Compacting Concrete) method was used to manufacture this kind of concrete. Results: The results of Slump Flow T50 test for 50% and 60% Styrofoam variations are 64 cm and 59 cm, while the concrete weight-volumes are1387.7 kg/m3 and 1259.4 kg/m3. Compressive strength test for both variations are 42.62 Kg/cm2 and 31.71 kg/cm2. Stiffness values for both variations are 1434.7 N/mm and 1125 N/mm. This study also analysed the maximum length of the panel wall in which for 50% Styrofoam variation is 4 m and 60% Styrofoam variation is 3.2 m. Applications/ Originality/ Value: Research on Styrofoam concrete hollow panel walls incorporated with high volume fly ash is significant since it opens the possibility to reduce the Styrofoam waste.
Highlights
The wall is one of the important elements in a high rise building or house
Styrofoam content and 60% Styrofoam content meet the requirements of the Slump flow test standard for Self-Compacting Concrete (SCC)
This result is possibly caused by higher gravitational force for 50% Styrofoam content in which more fine aggregate was used rather than 60% Styrofoam content the above result is in line with the research of Agus and Slamet (2010) that adding the amount of Polypropylene fibres to the concrete mix will reduce the value of workability
Summary
The wall is one of the important elements in a high rise building or house. The walls are constructed using red bricks or concrete bricks, but the process requires a long time and requires a lot of workers. One of the innovations is to make a panel- wall which is casted prior instalment to the construction site. The advantage of wall panels is more efficient in installation time because the installation is easier in comparison to brick, so that it will shorter the construction duration and reduce the number of human resources in its installation. Previous research about panel wall using thin concrete board and Styrofoam reinforced with bamboo reinforcement has been proven to be an alternative building element for masonry block wall, especially in high rise buildings or earthquake-prone areas (Hatta, 2006)
