Bu çalışmada,
vollastonit katkılı yüksek performanslı harçların (YPH) taze ve mekanik özellikleri
deneysel olarak incelenmiştir. İlk aşamada vollastonit mineralinin literatür
çalışmaları dışında belirlenen özel bir yöntemle sentetik olarak üretimi
yapılmış, ikinci aşamada ise sentetik vollastonit YPH üretiminde
kullanılmıştır. Vollastonit katkılı yüksek performanslı harçların (VYPH)
üretimi 0,33 sabit su/bağlayıcı (çimento+vollastonit) oranıyla, 132±10 mm sabit
bir yayılma çapıyla ve yüksek oranda su azaltıcı katkı (süper akışkanlaştırıcı)
kullanılarak gerçekleştirilmiştir. İlk olarak, kontrol harcı sabit su/bağlayıcı
oranı ile üretilmiş ve daha sonra sentetik vollastonit sırasıyla, %3, %6, %9 ve
%12 oranlarında her defasında çimentonun yerine ikame edilmiştir. Üretilen
harçların sarsma tablasında yayılma çapı ölçülmüştür. Sonrasında, harçlara
basınç ve eğilme testlerinin yanı sıra ultrasonik titreşim hızı testi 28. günde
uygulanmıştır. Deney sonuçlarına göre, vollastonit miktarının artmasıyla
yayılma çapı giderek azalmış ve mekanik özellikler %9’a kadar iyileşmiştir.
