تأثير إضافة غبار نوى التمر (DSD)‎ على خواص الطابوق الطيني

Abstract EN

This investigation is conducted to study the effects of adding of dust and burnt of Date Seeds Powder on properties of clay brick.

The soil was taken from Al-Furat brick plant in Hilla with percentages (21 , 36 , 43) (Sand , Silt , Clay ) respectively while for the added material were ( 5 , 10 , 20%) by weight of dry soil.

The specimens were made by special mold with dimension (5 , 6 , 12) cm and burnt at temperature (900o) .

The engineering properties of produced brick were investigated with two situation (nonburnt dust ) and (burnt dust).

The results illustrate that the addition of nonburnt added material lead to a increase in water absorption and an efflorescence except the percentage (20), while the density and the compressive strength were decreased .

Results with burnt dust showed that the increasing in water absorption and decreas in efflorescence , density and comprssine strength except at percentage (5) , It decreased the efflorsence clearly .
