Abstract

Concrete structure is one of the common construction materials in the world. The reliability in terms of performance, durability and cost effective are the major advantages in utilising concrete as construction material. However, due to time and workmanship, concrete is prone to deterioration. In this study, three main beam size of 400 mm x 1200 mm in size is evaluated in terms of structure integrity using Non-Destructive Test. Ultrasonic Pulse Velocity (UPV) is adapted to determine the concrete quality. For durability aspects, the utilisation of X Ray Fluorescence (XRF) with rapid carbonation kit is adapted. From this finding, one of the beams inspected is detected with poor quality. This is supported by visual for crack detection and voids in all beam. Elementary for concrete quality for all beams is confirmed using XRF and supported with carbonation kit. In conclusion, the outcome from NDT proves to determine any structure failure and factors contribute to the problem. Furthermore, the solutions to the problem can be identified.

Highlights

Nondestructive test is a method of testing existing concrete structures to assess the strength and durability of concrete structure
Major elements to be analysed is calcium, silica, alumina carbon, ferum and others. This is one of the important methods that can support the Non-destructive testing (NDT) test which can focus on the specific elements for every detail construction material [11]
Ground-penetrating radar (GPR) is a method that transmits radar signal pulse into image. It is an NDT testing, focusing on the detail embedded in the macrostructure of construction materials

Summary

Introduction

Nondestructive test is a method of testing existing concrete structures to assess the strength and durability of concrete structure. Conventional strength test does not give idea about the durability and performance of the actual concrete in the structure This gave the impetus to the development of non-destructive methods for testing structural concrete in-situ [10]. This is one of the important methods that can support the NDT test which can focus on the specific elements for every detail construction material [11] Those elements represent the concrete quality by identifying the development of binder, bonding and pores in the microstructure of concrete. Ground-penetrating radar (GPR) is a method that transmits radar signal pulse into image It is an NDT testing, focusing on the detail embedded in the macrostructure of construction materials. To confirm on the final compressive strength, the destructive compressive strength from core sample need to be done
