Which is harder to remember abstract ideas or concrete examples?
This episode was funded by The Wellcome Trust. Today, we are talking about concrete examples. Abstract ideas and concepts are harder to remember than those that are concrete (1). One way of getting around this issue is to use concrete examples to illustrate abstract ideas. For a concrete example of a concrete example, see this post .
How to predict the strength of a concrete mix?
Solving two simultaneous equations at two different ages while performing either design or trial concrete mix is a method that could be used to define the two constants. Other method is based on concrete strength at 28-day age. The proposed model was studied for different concrete mixes.
Which is an example of a concrete example?
For a concrete example of a concrete example, see this post . Novices will tend to focus on the surface features of the examples you give them.
When to consider increase in compressive strength of concrete?
Most codes of practice do not consider the increase of strength beyond 28 days for design purposes [ACI [2], ECP [3], …].
Explanation: A concrete example is an example that can be touched or sensed as opposed to an abstract example which can’t be. Let’s say that I’m trying to describe addition.
Why is it important to know the constituent properties of concrete?
Basic knowledge of concrete mixes, installation, weathering, and the other factors that can affect how it ages, in addition to the illustrations and photo examples provided here, will give inspectors the best chance of making sound decisions and recommendations to their clients. Constituent Material Properties
What happens to concrete when it is corroded?
When steel corrodes, the resulting rust occupies a greater volume than the steel. This expan- sion creates tensile stresses in the concrete, which can eventually cause cracking, delamination, and spalling (Figs. 1 and 2). Steel corrodes because it is not a naturally occurring material.
