Beton merupakan salah satu bahan konstruksi bangunan. Campuran beton terdiri dari semen, air, agregat dan bahan tambah bila diperlukan. Material semen dalam beton sangat penting dikarenakan semen berfungsi sebagai bahan pengikat antara agregat kasar dan agregat halus. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan semen Portland Cement Composit (PCC) dan semen Tipe I diproduksi oleh semen Andalas terhadap kuat tekan beton berdasarkan umur beton pada campuran beton dengan nilai Faktor Air Semen (FAS) 0,50 dan 0,55. Perencanaan campuran beton menggunakan metode American Concrete Institute 211.1-91. Ukuran maksimum agregat adalah 31,5 mm. Benda uji yang digunakan pada penelitian adalah silinder beton berdiameter 15 cm dan tinggi 30 cm. Pada penelitian ini umur pengujian kuat tekan adalah 3, 7, 14, 21 dan 28 hari dengan FAS 0,50 dan 0,55. Jumlah sampel untuk semua FAS pada setiap pengujian kuat tekan beton adalah 30 buah benda uji untuk masing-masing tipe semen. Berdasarkan hasil pengujian kuat tekan rata-rata beton FAS 0,50 yang menggunakan semen tipe I untuk umur 3, 7, 14, 21 dan 28 hari berturut-turut adalah sebesar 193,34 kg/cm2, 203,72 kg/cm2, 229,18 kg/cm2, 248,99 kg/cm2 dan 272,57 kg/cm2. Sedangkan Untuk semen PCC pada umur yang sama kuat tekannya adalah sebesar 139,58 kg/cm2, 169,77 kg/cm2, 202,78 kg/cm2, 220,69 kg/cm2 dan 249,93 kg/cm2. Untuk FAS 0,55 yang menggunakan semen tipe I untuk umur 3, 7, 14, 21 dan 28 hari berturut-turut adalah sebesar 182,97 kg/cm2 , 202,78 kg/cm2, 218,81 kg/cm2, 235,79 kg/cm2 dan 267,85 kg/cm2. Sedangkan Untuk semen PCC pada umur yang sama kuat tekannya adalah sebesar 149,02 kg/cm2, 169,77 kg/cm2, 177,31 kg/cm2, 209,38 kg/cm2 dan 243,33 kg/cm2. Ditinjau dari jenis semen yang digunakan terlihat bahwa beton dengan menggunakan semen adalas tipe I perkembangan kuat tekan betonnya lebih tinggi dibandingkan dengan PCC baik pada FAS 0,50 dan 0,55 pada umur yang sama.

Set Up

ABSTRACTPortland cement concrete (PCC) structures deteriorate with age and need to be maintained or replaced. Early detection of deterioration in PCC (e.g., alkali-silica reaction, freeze/thaw damage, or chloride presence) can lead to significant reductions in maintenance costs. However, it is often too late to perform low-cost preventative maintenance by the time deterioration becomes evident. By developing techniques that would enable civil engineers to evaluate PCC structures and detect deterioration at early stages (without causing further damage), optimization of life-cycle costs of the constructed facility and minimization of disturbance to the facility users can be achieved.Nondestructive evaluation (NDE) methods are potentially one of the most useful techniques ever developed for assessing constructed facilities. They are noninvasive and can be performed rapidly. Portland cement concrete can be nondestructively evaluated by electrically characterizing its complex dielectric constant. The real part of the dielectric constant depicts the velocity of electromagnetic waves in PCC. The imaginary part, termed the “loss factor,” describes the conductivity of PCC and the attenuation of electromagnetic waves.Dielectric properties of PCC have been investigated in a laboratory setting using a parallel plate capacitor operating in the frequency range of 0.1 to 40.1MIHz. This capacitor set-up consists of two horizontal-parallel plates with an adjustable separation for insertion of a dielectric specimen (PCC). While useful in research, this approach is not practical for field implementation. A new capacitor probe has been developed which consists of two plates, located within the same horizontal plane, for placement upon the specimen to be tested. Preliminary results show that this technique is feasible and results are promising; further testing and evaluation is currently underway.

Mechanical And Microstructural Properties

This study reported that the addition of nano-silica enhances the mechanical characteristics of concrete as its compressive, flexural and tensile split strengths are increased. As a comparison mixture to equate it along with nano-modified concrete, ordinary samples of Portland cement (OPC) have been utilized. Herein, upto 6.0 percent of OPC has been substituted by nanosilica. In fact, the introduction of nanosilica improves mechanical and microstructural characteristics of concrete by significantly (28 to 35%). The finding therefore, indicated that partly replacing OPC with up to 5 percent nanosilica increases the mechanical and microstructural properties cured up to ninety days as opposed to the standard OPC mix.
