May 18, 2018 0183 32 Concrete being the major consumable material after water makes it quite inquisitive in its nature The strength of concrete is majorly derived from aggregates, where-as cement and sand contribute binding and workability along with flowability to concrete This is an in-depth article on Compressive Strength of Concrete...
A statistical analysis of the errors reveals a drastic improvement compared to the linear fracture theory as well as the strength theory The applicability of fracture mechanics to concrete ,...

Compressive strength of concrete cube test provides an idea about all the characteristics of concreteBy this single test one judge that whether Concreting has been done properly or not Concrete compressive strength for general construction varies from 15 MPa 2200 psi to 30 MPa 4400 psi and higher in commercial and industrial structur...
Curing plays an important role on strength development and durability of concrete Curing takes place immediately after concrete placing and finishing, and involves maintenance of desired moisture and temperature conditions, both at depth and near the surface, for extended periods of time...
Plastic Theory of Reinforced Concrete Design by Charles S Whitney, Serial Information Transactions of the American Society of Civil Engineers , 1942, Vol 107, Issue 1, Pg 251-282...
Concrete thinkers only have a generalized concept for all things On the other hand, abstract thinkers have a very specific concept of things When compared to concrete thinking, abstract thinking is about understanding the multiple meanings When abstract thinking is based on ideas, concrete thinking is based on seeing and also on facts...
Concrete thinking is the first form of thinking children master Very young babies think extremely concretely, and most research indicates that they cannot conceive of an object as existing if it ....
A gradual accumulation of inelastic strain can be most conveniently described in terms of the so-called intrinsic time, whose increment depends on the time increment as well as the strain increments, and was previously developed for metals and is extended herein to concrete...
The Theory-Theory of Concepts The Theory-Theory of concepts is a view of how concepts are structured, acquired, and deployed Concepts, as they will be understood here, are mental representations that are implicated in many of our higher thought processes, including various forms of reasoning and inference, categorization, planning and decision making, and constructing and testing ,...
Jean Piaget s theory of cognitive development suggests that children move through four different stages of mental development His theory focuses not only on understanding how children acquire knowledge, but also on understanding the nature of intelligence...
Theory of Creep and Shrinkage in Concrete Structures A Precis of Recent Developments Zdenllk P Ba ant Northwestern University, Evanston, illinois Contents 1 Introduction 2 Basic Experimental Facts Relating to Creep and Shrinkage 3 Concrete Approximated as an Aging Viscoelastic Material 31 Integral-Type Creep Law...
a similified theory which apptars to give realistic results over the complete range of sizes, including the transition range, and can be brought in a good agreement with 156 essentially all available fracture test data for concrete, a goal not yet achieved in the existing literature The reason for the deviations from linear fracture...
Age of concrete The degree of hydration is synonymous with the age of concrete provided the concrete has not been allowed to dry out or the temperature is too low In theory, provided the concrete is not allowed to dry out, then it wil always be increasing albeit at an ever reducing rate...
The educational implication of Piaget s theory is the adaptation of instruction to the learner s development level It is important that the content of instruction needs to be consistent with the developmental level of the learner The teachers main role is the facilitation of learning by providing various experiences for the students...
The concrete operational stage is the third stage of Piaget s theory of cognitive development This stage, which follows the preoperational stage, occurs between the ages of 7 and 11 preadolescence years, and is characterized by the appropriate use of logic During this stage, a child s thought processes become more mature and adult like...
Apr 01, 2005 0183 32 COMPOSITES AND CONCRETE The benefits of composite materials are well established in concrete reinforcement and construction Source AltusGroupC-GRID is a heavy tow carbon/epoxy grid used as a replacement for secondary steel reinforcing grid in precast concrete tilt-up panels and architectural applications Grid size varies depending on ....
Concrete and abstract thought in psychology Jean Piaget uses the terms concrete and formal to describe two different types of learning Concrete thinking involves facts and descriptions about everyday, tangible objects, while abstract formal operational thinking involves a mental process...
Dec 19, 2015 0183 32 THEORY Two types of tests are carried out to determine whether the concrete produced does follow the specification given They are compacting factor test, slump test and vebe consistometer test which are for wet concrete Whereas for hardened concrete, they are cube compression test and flexibility compression beam test...
Plain Reinforced Concrete Theory Plain Reinforced Concrete Theory Concrete Concrete is a mixture of cement, fine and coarse aggregate Concrete mainly consists of a binding material and filler material If filler material size is < 5mm it is fine aggregate and >5mm is coarse aggregate...
The theory presents a cyclical model of learning, consisting of four stages shown below One may begin at any stage, but must follow each other in the sequence Concrete experience or DO The first stage, concrete experience CE , is where the learner actively experiences an activity such as a ,...
Concrete step of CPA Concrete is the doing stage During this stage, students use concrete objects to model problems Unlike traditional maths teaching methods where teachers demonstrate how to solve a problem, the CPA approach brings concepts to life by allowing children to experience and handle physical concrete objects...

This article describes the discovery of a set of biologically-driven semantic dimensions underlying the neural representation of concrete nouns, and then demonstrates how a resulting theory of noun representation can be used to identify simple thoughts through their fMRI patterns We use factor analysis of fMRI brain imaging data to reveal the biological representation of individual concrete ....
