Pengaruh Natrium Tripolyphosphate (Na5p3o10) Terhadap Sifat Mekanik Beton Cor…

ABSTRACT Compressive strength and split tensile strength are important parameters of concrete strength. This resarch was conducted to examine the effect of adding Sodium Tripolyphosphate (Na5P3O10) on the mechanical properties of Under-Water Concrete (UWC). Variation of Na5P3O10 used is by ading 5%, 10% and 15% of cement weight, and adding stone crush as filler at 10% of fine aggregate weight.…
