Abstract

This paper described an investigation and evaluation which was carried out in the United Kingdom-UK, on the properties of masonry building block materials that incorporate waste materials, namely: steel slag, crushed glass, coal fly ash, rice husk ash (RHA), incinerator sewage sludge ash (ISSA), municipal solid waste incinerator bottom ash (MSWIBA) or shortened as IBA, bound with bitumen or asphalt, named as Bitublock. The binder used was 50 pen bitumen. The properties of the blocks evaluated were: compressive strength, density, porosity, initial rate of suction (IRS), creep, and volume stability. It was found that the Bitublock performance can be improved by optimizing porosity and curing regime. Compaction level of 2 MPa and curing regime of 200°C for 24 hours gave satisfactory bitublock performances that at least comparable to concrete block found in the United Kingdom (UK). The Volume stability (expansion) of the unit is affected by environment relative humidity.

Abstract

This paper covers results of laboratory investigations on the volume stability of masonry units incorporating waste materials bound with bitumen (Bitublocks), due to moisture adsorption, thermal exposure and vacuum saturation. The materials used were steel slag, crushed glass, coal fly ash, and 50 pen bitumen. The samples were produced in hot mix method, compacted, then exposed to moist and temperature. It was found that moisture adsorption from the environment caused the Bitublock to expand. The samples with less intense curing regime experienced lower expansion and became stable faster, and vice versa. Under thermal condition (at 70°C), the samples with less intense curing regime underwent higher expansion, and vice versa. They were also highly reversible. Their volume stability was found unique under water exposure. The expansion on first vacuum saturation cycle was irreversible, then largely reversible on the following cycles.

Abstract

Masker adalah perlindungan pernafasan yang digunakan sebagai metode untuk melindungi individu dari menghirup zat-zat bahaya atau kontaminan yang berada di udara. Meskipun masker sangat diperlukan untuk menghindari penyebaran virus Corona, namun pembuangan masker mengancam lingkungan. Masker medis terdiri dari tiga lapisan, lapisan luar dan lapisan dalam adalah kain non-woven yang tahan air dan lapisan tengah adalah bahan yang meleleh. Sebagian besar, komposisi kimia dari masker medis adalah polipropilena. Pada review ini akan dibahas penggunaan limbah masker yang mengandung polipropilena sebagai bahan aditif dalam pembuatan campuran aspal. Metode yang digunakan adalah studi literatur dari peneliti terdahulu dan analisis penambahan limbah masker yang mengandung polipripilena yang berpengaruh terhadap campuran aspal. Sumber utama refrensi artikel ini berasal dari Research Gate, Science Direct, dan Google Scholar. Ditemukan bahwa unsur senyawa yang paling dominan pada masker medis adalah Si (Silika) sebesar 59,11%. Penambahan silika pada campuran aspal dapat meningkatkan ketahanan terhadap kerusakan alur, peningkatan nilai modulus, dan umur fatigue.
