Abstract

The research objective was to provide an overview of the engineering inspection methods used in determine the quality of repair results and the quality of the results of concrete repair based on the results of concrete repair what has been done. The research method is carried out by engineering inspection methods which include visual tests and rebar test of concrete surface, compressive strength test with hammer test, test for concrete homogeneity with UPV test, test profometer concrete thickness blanket, cast drilled concrete core sampling, tensile test and concrete connection carbonation test of concrete surfaces with phenopthalein solution. The results of the research are chipping and grouting with specifications of microconcrete flowable material and repaired concrete surface protection with a thick mastic shield coating material specifications min. 300 micron DFT has been proven improve the strong quality of existing concrete by 69.40% from the compressive strength of the installed concrete design. Method Technical inspection, repair methods and specifications of the material used can be replicated for repairs damage and to determine the quality of similar repairs elsewhere.

Abstract

The aim to be achieved from this research activity is to provide an overview of the factors and causes of cracks, labar and crack depth on the concrete slab of the vehicle floor of the parking building and recommendations for improvement methods. This research method is a used research method and is a success story of crack evaluation and handling methods that have been carried out. The results showed that the crack width that occurred was 0.624-1.022 mm vs. 0.33 mm, out of tolerance. The results of the deflection measurements also show an average deflection in the concrete slab of the vehicle floor is 5.8-10.5 Cm and indicates that the crack has reached the concrete reinforcement, out of tolerance. With the results of this study, it is recommended that improvements be made with crack injection methods using low-pressure injection tools and specifications of an epoxy resin material.

Abstract

Tujuan penelitian ini adalah memberikan gambaran spesifikasi material flowable micro concrete dan peralatan yang digunakan pada perbaikan spalling dan delaminasi beton pondasi pompa boiler feed water di Unit Utilities Kilang Balikpapan. Metode perbaikan kerusakan beton pondasi akibat delaminasi dan spalling dilakukan dengan chipping lapis permukaan beton pondasi beton yang terdegradasi, cleaning dengan water jeting, melaburi dengan bonding, grouting dengan sagola chamber, curing dengan selalu menjaga tetap dalam kondisi lembab dan coating dengan amine-cured, pitch free epoxy coating. Hasil perbaikan menunjukkan spesifikasi material flowable microconcrete terbukti cocok dan sesuai digunakan untuk mengatasi masalah kerusakan beton pondasi yang rusak akibat delaminasi dan spalling. Untuk menjamin keberhasilan metode kerja grouting dengan flowable micro concrete telah dibuat metode kerja baku dan teregister di Unit Kualitas manajemen PT. Pertamina RU V dan telah direplikasi di unit kerja lain yang mengalami permasalahan sejenis.
