Effect of Aggregate Content on the Concrete Compressive Strength - Ultrasonic Pulse Velocity Relationship

Abstract

This paper investigates the relationship between the ultrasonic pulse velocity (UPV) and the compressive strength of concrete. The specimens used in the study were made of concrete with varied aggregate contents from 1000 to 1400 kg/m 3 . The specimens were made and tested at the Hawler Construction Laboratories (HCLabs) in Erbil, Kurdistan Region of Iraq. The UPV measurement and compressive strength tests were carried out at the concrete age of 28 days. The experimental results show that the relationship between UPV and the compressive strength of concrete is significantly influenced by the coarse aggregate content. Relationships are established for the range of contents of coarse aggregates and discussed.

RPC Effect of Crude Oil Products on the Mechanical Characteristics of Reactive-Powder and Normal-Strength Concrete

“…The grading of the fine aggregate utilized is illustrated in Table 3. The results illustrate that the grading of fine aggregate after omitting the large size of the particle (>600 µm) was within the Iraqi Specification requirements (IQS No.45/1984) [29]. The physical tests of fine aggregate that involve specific gravity, absorption, fineness modulus, sulfate content and content of fine materials are given in Table 4.…”

Analisis Hubungan Kecepatan Gelombang Dengan Kuat Tekan Beton Menggunakan Metode UPV

“…Namun untuk perhitungan kuat tekan beton dengan kualitas tinggi, seperti beton A, B, C, D, dan F memiliki kesalahan perhitungan rata-rata sebesar 3,04% dengan kesalahan minimum sebesar 0,58% dan kesalahan maksimum sebesar 6,63%. Pengujian kuat tekan beton menggunakan sistem UPV dapat dipengaruhi oleh banyak variabel, seperti perbandingan campuran, jenis agregat, umur beton, dan kadar air [9]. Hal ini juga dapat menyebabkan anomali yang sangat penting.…”
