“…SF is effective in reducing alkalinity at an early age, meanwhile FA become effective at later ages [2]. The effectiveness of EPP in mitigating ASR can be attributed to pozzolanic activity [6,7], possessed by the material. In suppressing expansion, the porous nature of EPP might play an important role by providing a distributed air bubble system that accommodates expansive gel in concrete [7].…”

Abstract. ASR suppression by FA, SF, EPP, FA in combination with SF and EPP were evaluated by both mortar bar and concrete prism test. Mortar bars were made based on JIS A 1146, meanwhile concrete prism bars were casted in accordance with Rilem AAR-3. Both specimens were stored in 40 o C 100% R.H. controlled room. Mortar and concrete mixtures used reactive aggregate in pessimum proportion. The results indicated that FA in combination with SF and EPP showed smaller expansion compared to FA. The best of concrete mixtures in reducing expansion is combination of FA with SF (FA15SF10).

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.

“…For the mortar without MP (Series A), the water to binder (W/B) of the Control mortar is 0.65 and those of F2P1 and F2P2 mortar with 0.1 and 0.2 of EP are 0.84 and 1.04. The EP has very light, porous and very variable in the particle shape, therefore, it substantially increased the water demand of the mixes [15]. The addition of MP tends to slightly reduce the water demand through the aid of air void in improving the workability [16].…”

ABSTRACT:Cracking of masonry and plastering mortars of clay brick wall was a major problem in the hot climate area. The problem was the worst for the wall made of lightweight blocks. In this research, masonry and plastering mortars made from Portland cement, fly ash, expanded perlite, mortar plasticizer, and sand were tested. The testing program included the determination of water demand, setting time, water retention, compressive strength, splitting tensile strength, density, and elastic modulus. For the masonry mortar, the mixes with high calcium fly ash with or without plasticizer could be used with required properties and reduced cost. The mix of expanded perlite gave water retention over the required 70%. The mix containing fly ash and 0.2% plasticizer gave water retention slightly less than 70%. It was recommended that the mix with expanded perlite should be used for indoor plastering and the mix with fly ash and plasticizer should be used for outdoor plastering.
