Kesan penggunaan ggbs terhadap kekuatan mampatan, keliangan dan kebolehtelapan konkrit

Kesan penggunaan ggbs terhadap kekuatan mampatan, keliangan dan kebolehtelapan konkrit / Mohd Zakry Ibrahim
Kesan penggunaan Jermang Relau Bagas (GGBS) terhadap kekuatan mampatan, keliangan dan kebolehtelapan konkrit telah dikaji. GGBS digunakan dengan cara penggantian terus terhadap simen melalui kaedah jisim ke jisim pada tahap penggantian tertentu. Empat campuran konkrit pada tahap penggantian GGBS sebanyak 0%, 20%, 50% dan 70% disediakan. Nisbah air/pengikat yang malar untuk setiap campuran konkrit digunakan bagi mengasingkan kesan tahap penggantian GGBS. Keputusan kajian secara amnya menunjukkan kesan penggunaan GGBS mengurangkan kekuatan awal konkrit dengan lebih tinggi tahap penggantian lebih tinggi pengurangan berlaku. Sebaliknya, kekuatan jangka panjang konkrit meningkat dengan penambahan GGBS. Keputusan juga menunjukkan bahawa penambahan GGBS meningkatkan keliangan dan kebolehtelapan jangka pendek konkrit, tetapi mengurangkan keliangan dan kebolehtelapan jangka panjang konkrit. Oleh itu, kesan penggunaan GGBS berpotensi untuk meningkatkan kekuatan dan ketahanlasakan konkrit. _______________________________________________________________________________________________________ The influences of Ground Granulated Blastfurnaced Slag (GGBS) on compressive strength, porosity and permeability of concrete has been investigated. The GGBS was used partly replace the cement by direct replacement method on mass – for – mass basis. Four concrete mixes with GGBS replacement levels of 0%, 20%, 50% and 70% were prepared. A constant water/binder ratio was use for all concrete mixes so as to isolate the effect of GGBS replacement levels. The result generally show that the effect of GGBS is to reduce the early age strength of concrete with higher reduction at higher replacement levels. On the other hand, long term strength is enhanced with the addition of GGBS. The result also show that the inclusion of GGBS increase the early age porosity and permeability of concrete, but reduced the long term porosity and permeability. Hence, the use of GGBS could potentially enhance the strength and durability of concrete.
