Graphical Representation - Types, Rules, Principles and Merits

Graphical Representation is a way of analysing numerical data. It exhibits the relation between data, ideas, information and concepts in a diagram. It is easy to understand and it is one of the most important learning strategies. It always depends on the type of information in a particular domain. There are different types of graphical

Mixing Concrete - Illustrative Mathematics

In reality, the volume of the mixture may actually be less than that as cement particles settle into the spaces between the grains of sand. It is important for students to understand that they must explicitly make this assumption, and that for some contexts this is a reasonable assumption (e.g. mixing water with juice concentrate) and others it

The Maturity Method: From Theory to Application

concrete temperature was the same for all specimens, and specimens were moved into the different temperature chambers after molding had been completed. In a later study at NBS, the applicability of the maturity method under simulated field conditions was investigated [Carino et al. 1983b]. Three different concrete mixtures were used to

Manufacturing Light Concrete with PET Aggregate

The manufacture of concrete using a polymer instead of a stony coarse aggregate known as gravel is presented. Polyethylene terephthalate (PET) is the polymer used, recycling soft drink containers with sufficient tenacity . PET is a material commonly used by engineers as a structural element, not as an aggregate. The research work revealed that PET aggregate produces good quality mixtures with

Microstructure of Concrete | IntechOpen

Oct 27, 2015 · Concrete is a composite material that consists of a binding medium and aggregate particles and can be formed in several types. It may be considered to consist of three phases: a cement paste, the aggregate, and the interfacial transition zone (ITZ) between them. In addition to ordinary Portland cement, the essential components of the base of concrete are aggregates and water. For practical

Mesoscopic modeling of the impact behavior and

This study presents the numerical analyses conducted to investigate the impact behavior of different porous concretes, which have also been cast and tested experimentally. For a realistic representation of the real porous concretes containing arbitrary shaped air pores, a mesh generation code was developed in which the aggregates in the mixtures were directly extracted through computed tomography.
