ASTM C1604
Full Name
ASTM C1604 – Standard Test Method for Obtaining and Testing Drilled Cores of Shotcrete
Scope
ASTM C1604 provides a standardized method for obtaining, preparing, and testing cores drilled from shotcrete. The scope of the standard includes:
- Obtaining cores: it details the procedures for drilling cores from shotcrete structures, whether during construction or from existing structures. This includes guidelines for core location, drilling techniques, and core size.
- Preparing cores: it outlines the steps involved in preparing the drilled cores for testing, such as cutting to length, capping the ends, and conditioning the specimens.
- Testing cores: the standard specifies the methods for testing the cores to determine their length, compressive strength, or splitting tensile strength. It provides guidance on testing apparatus, procedures, and calculations.
The information obtained from testing cores according to ASTM C1604 can be used for various purposes, including:
- Quality control: assessing the quality of shotcrete during construction or evaluating the condition of existing shotcrete structures.
- Design verification: verifying the design assumptions and ensuring that the shotcrete meets the required strength and durability criteria.
- Research and development: investigating the properties of different shotcrete mixtures and application techniques.
In essence, ASTM C1604 serves as a valuable tool for evaluating the performance of shotcrete in both new and existing structures, contributing to the safety and durability of infrastructure projects.
