values in the chart or to other concrete being tested under the test procedure. What are the Factors that Influence Test Results? There are many factors that may affect the accuracy of the test procedure. We have found that the age and curing of the test specimen affects the results dramatically.

Fresh concrete test data such as slump and air content can help indicate possible causes and guide the troubleshooting investigation. Was excess water added? Was the air content too high or too low?

What is a concrete test?
Accurate test results are not possible without an accurate sample. ASTM C172 lays out the accepted methods for obtaining a representative sample of fresh concrete for tests, including slump, air content, unit weight, temperature, and the molding of strength specimens.
A. According to section 19.2.1.3 of ACI 318-19 the specified compressive strength shall be based on the 28-day test results unless otherwise specified in the construction documents. 3- or 7-day test results are used to monitor early strength gain, especially when high early-strength concrete is used. However, 3- and 7-day test results are not ...
Table 4.4 provides control standards for concretes with fc′ exceeding 5000 psi (35 MPa). These control standards were adopted based on examination and analysis of compressive strength data by ACI Committees 214, Evaluation of Strength Tests, and 363, High-Strength Concrete. Strength tests were conducted using.

The strength of concrete is considered satisfactory provided that: • Average of three consecutive strength tests equals or exceeds the specified compressive strength f´c. • No strength test result falls below f´c by more than 3.5MPa when f´c is 35MPa or less, or by more than 0.10 f´c when f´c is more than 35MPa.
Man I just finished Dragged across concrete and I have to agree 100% with you. Didn't love Bone Tomahawk as much as Brawl and this one but I am right there with you when you say "he's a must see filmmaker for me." I will now be looking for anything Zahler puts out. The only other director I do that for is Tarantino. Can't wait for his next film.
