Yüksek plastisiteli kil zeminin mühendislik özelliklerine inþaat atýklarýnýn etkisi

Bu çalýþmada, inþaat atýklarýnýn yüksek plastisiteli bir kilin bazý mühendislik özelliklerine olan etkisi araþtýrýlmýþtýr. Bu kapsamda öncelikle zemin numunesi ve inþaat atýklarýnýn kimyasal özellikleri belirlenmiþtir. Kile aðýrlýkça %2, %5, %10, %15, %20, %25, %30 ve %35 oranlarýnda No. 40 elek altý inþaat atýklarý karýþtýrýlarak hazýrlanan numuneler üzerinde kývam limitleri ve standart kompaksiyon deneyleri yapýlmýþtýr. Ek olarak optimum su muhtevasý ve maksimum kuru birim hacim aðýrlýk þartlarýnda sýkýþtýrýlmýþ katkýsýz kil ile %5, %10, %20 ve %30 katkýlý numuneler üzerinde, optimum su muhtevasý ve maksimum kuru birim hacim aðýrlýk þartlarýnda sýkýþtýrýlarak sabit hacimli þiþme ve serbest basýnç deneyleri de yapýlmýþtýr. Deney sonuçlarý, þiþen kile %10-%20 oranýnda inþaat atýklarýnýn eklenmesinin þiþme potansiyelinin azaltýlmasýnda ve serbest basýnç mukavemetinin arttýrýlmasýnda ideal sonuçlar verdiðini göstermiþtir.

Effect of construction waste to engineering properties of high Plasticity clay soil

In this study, it is investigated effect of construction waste to some engineering properties of a high plasticity clay. For this reason, some chemical properties of the soil sample and construction waste are determined. The consistency limits and standard compaction tests are carried out on the clayey samples in weight with the ratios 2%, 5%, 10%, 15%, 20%, 25%, 30% and 35% of the construction waste passing from the sieve of No 40. The constant-volume swelling and unconfined compression tests are also conducted on both pure clay and the mixtures in weight with the ratios 5%, 10% 20% and 30% of the construction waste compacting at the optimum water content and maximum dry density. From the results of test, it is found that the construction waste can be effectively used at a ratio of 10%-20% for both decreasing the swelling potential of clay and increasing the unconfined compression strength of that.
