“…The specimens with 10% ground basaltic pumice exhibited the highest sulfate resistance. Binici et al [18] partially replaced sand, in concretes, with GBFS at levels of 0%, 40%, 60% and 80%, by weight. They studied the abrasion resistance of different types of concrete.…”

“…Since the toughness of usual wood used as probs in mines is about 1500 kg.mm [24], the lightweight aggregate concrete with 1 and 2% steel fiber have a toughness about 3 and 6 times greater than wood, respectievly. In this study the strength and ductility of lightweight aggregate concrete material are invetigated while other researchers has shown that this material is also durable against the aggressive environemt [25][26][27]. Due to the suitable strength and durability propertis of the lightweight aggregate concrete and the following simple comprassion someone may conclud that it could be a reasonable choice as a prop material.…”

Several devices are used to provide support in an underground space. Wooden prop is generally employed for the purpose of passive secondary or short-term support of the mine roadway roof and sides. The wooden prop has various known usage limitation, including low strength, deterioration of wood in humid environment, poor ductility, and generally low service life. Substitution of the wooden prop with a prop made with a more suitable material could thus yield important advantages. In this study, lightweight aggregate concrete (LWAC) is proposed to be used as a prop material. Since lightweight aggregate has a relatively low ductility, steel fibers are used in this investigation to achieve enhanced ductility levels. Five mixtures of fiber reinforced lightweight aggregate concrete were considered with different steel fiber percentages and pumice lightweight aggregates produced in Iran. The density, compressive, tensile and flexural strength as well as the toughness index of different fiber reinforced lightweight aggregate concrete materials were measured in order to assess their potential as replacement for wood in prop production. The experimental results indicated that the density of lightweight aggregate concrete is higher than wood. Since the strength and toughness of LWAC is significantly more than those of wood, the weight of a LWAC element with the same strength turns out to be 22 percent less than the wood element. Hence, wooden prop may be replaced with lightweight aggregate concrete prop to achieve improved service life and ductility while reducing the weight of the prop.

ÖzetBu çalışmada, atık mukavva, alçı, pomza, perlit, vermikülit ve zeolit ile yapılan kompozitlerin yangın direnci ASTM E 160-50'ye göre belirlenmiştir. Numunelerin birim hacim ağırlıkları, su emme oranları ile ısı iletim katsayısı ve ultra ses geçirgenlik katsayısı bulunmuştur. Atık mukavva, alçı, pomza, perlit, vermikülit ve zeolit ile yapılan kompozitlerin ısı iletim ve ultra ses geçirgenlik katsayısı oldukça düşük bulunmuştur. Test sonuçlarına göre en uzun yanma süresi üçlü karışımlardan elde edilmiştir. En kısa sürede yanan örnekler ise ikili karışımlardan özellikle alçı ve perlit katkılı olan örneklerdir. Sonuç olarak, atık mukavvanın alçı, pomza, perlit, vermikülit ve zeolitin ikili ve üçlü karışımlarıyla elde edilen kompozitlerin yangına yeterli direnç gösterdiği ve yanmayı geciktirdiği anlaşılmıştır. AbstractIn this paper, fire resistance of the composite made with waste cardboard, gypsum, pumice, perlite, vermiculite and zeolite was determined according to ASTM E 160-50. Unit weight, water absorption rate, ultra sonic penetration, heat conductivity and permeability coefficient of the samples was found. Thermal conductivity, ultra-sound transmission coefficient of composites made with zeolite, waste cardboard, plaster, pumice, perlite and vermiculite is very low. According to the test results the longest burn time were obtained from the triple mixes. Fire resistance of gypsum and perlite binary mixtures was lowest. As a result, it was found that the ternary and binary mixture made with waste cardboard, gypsum, pumice, perlite, vermiculite and the zeolite showed enough resistance to fire and by delaying burning.
