Pomza agregası ile üretilen düşük dayanımlı beton blokların bazı fiziksel ve mekanik özelliklerine hidrofob kilin etkileri

Year 2012, Volume: 25 Issue: 2, 111 - 115, 01.12.2012

Abstract

Alınış tarihi 3 Ekim 2012 Düzeltilme tarihi 6 Aralık 2012 Kabul tarihi 10 Aralık 2012 Hafif beton bloklar, işlenmiş doğal malzeme veya işlenmemiş gözenekli malzemeler kullanılarak üretilebilir. Bu çalışma, taşıyıcı veya taşıyıcı olmayan elemanların inşasında kullanılan hafif beton blokların yapımı için pomza hafif agregası ve hidrofob kilin kullanımını kapsamaktadır. Bu makalede pomza agregası Erzurum-Pasinler yöresinden temin edilmiş ve düşük dayanımlı beton blokların bazı fiziksel ve mekanik özellikleri incelenmiştir. Deney sonuçlarına göre, kuru birim ağırlığı 855 ve 1040 kg m-3arasında değişmekte iken, su emme % 15-% 22 arasında, numunelerinin 28 günlük basınç dayanımı 4,75 den 8,5 MPa arasında değişmektedir. Araştırmadan elde edilen sonuçlar, % 10 hidrofob kil katkısı ile üretilen örneklerin yük taşıyıcı uygulamalarda kabul edilebilecek yeterli dayanım ve düşük su emmeye sahip olduğunu göstermiştir. Düşük birim ağırlığından dolayı üretilen örnekler kırsal alanlardaki tarımsal yapıların yapımında depreme dayanıklı olmalarını da sağlamak için kullanılabilir

The effects of hydrophobe clay on some physical and mechanical properties of the low-strength concrete blocks produced with pumice aggregate

Year 2012, Volume: 25 Issue: 2, 111 - 115, 01.12.2012

Abstract

Light-weight concrete blocks (LCB) can be produced by using processed natural material or unprocessed porous materials. The present study covers the use of pumice lightweight aggregate (PLA) and hydrophobe clay to produce the LCB for use in construction of load-bearing or non-load bearing structural members. Pumice aggregate (PA) were supplied from Erzurum-Pasinler region. Some physical and mechanical properties of the specimens produced were investigated in this study. According to experimental results, while dry unit weight varies between 855 and 1040 kg m-3 with water absorptions between 15%-22%, 28-day compressive strength ranged from 4.75 to 8.5 MPa. Experimental test results showed that the specimens produced with 10% hydrophobe clay addition have sufficient strength and lower water absorption to be considered load-bearing block applications. Due to low unit weight, such specimens can be used to build earthquake-resistant agricultural structures in rural areas.
