PENGARUH VARIASI PENAMBAHAN AIR DAN SEMEN PADA SUATU PERENCANAAN CAMPURAN (MIX DESIGN) TERHADAP SUSUT BETON DAN KUAT TARIK BELAH BETON (SUATU PENELITIAN BETON DENGAN FAS 0,3, 0,4 DAN 0,5)
Abstract: Note that the addition
of cement in mixing concrete will increase the strength of concrete when water
is added only if the concrete strength will be decreased but increased
workabilitas concrete . This study aims to determine the effect of the addition
of water and cement for concrete and tensile strength dropped concrete sides .
Test substance used for testing concrete and tensile strength decreased
Shopping concrete cylinder diameter is 15 cm; 30 cm high by 72 . Cement Water
Factor (FAS ) used are 0.3 , 0.4 and 0.5 . In this research is the addition of
water and cement 0 % , 10 % , 20 % and 30 % respectively for the FAS. Where for
every percentage increase in water and cement made 6 test objects . Testing is
done in the space fell sheltered by looking at the results of curtailment
reading on the dial gauge test objects . Shop tensile strength testing done at
28 days , with an increase of 1 ton each . Stretching things a test read
tranducer tool mounted on the frame gauge connected to a data logger tool . The
results showed that the decreased stretch of concrete increases with the
increase in the percentage of water and cement penambahaan done , while for
increased tensile strength of the concrete sides of the optimum place on the
addition of water and cement by 20 % for each of his FAS . The analysis of
variance showed that there was significant influence between the percent
increase in water and cement to the sides of the concrete tensile strength .
Keywords: Addition of water
and cement; FAS; Shrinkage of concrete; split tensile strength of concrete
