Sep 01, 2012  The deformation of concrete specimens loaded at ages of 12, 16, 20, 24, 48 and 72 h were measured for 30% of the compressive strength at the age of loading. Furthermore, deformation measurements for loads of 20% and 40% of the compressive strength were also performed at the ages of 12 and 24 h. 2. Creep and shrinkage.

Highlights We study a high early-age strength SCC which reaches more than 60 MPa at 24 h. Deformation is measured for different age of loading and stress levels. Creep and the stress level are not directly related for early age loadings. Creep coefficient is somewhat well-predicted by the EC 2.

Abstract The age of loading and the stress level are important parameters in the precast/prestress industry as they are related to the time of each production cycle, as well as to the concrete deformation. For this reason, a study about the influence of the age of loading and the stress level on the deformation of a self-compacting concrete with a mix composition typically used in the ...

Aug 30, 2017  1. Introduction. Creep is an important time-dependent behavior of concrete and can result in adverse effects, such as increasing deformation, redistributing stress and internal force, and even structural failure , , on structures.To most concrete structures, creep effects caused by early age loading are universal, and early age creep is more significant than creep in hardened concrete , , .

Early Age Creep and Shrinkage of Concrete with Shrinkage ...

Early age creep and shrinkage are primary factors that influence premature cracking of concrete affecting the durability and performance of concrete structures. Shrinkage of concrete causes tensile stress development while tensile creep works as a stress relaxing mechanism and relieves part of the stress developed due to shrinkage.

Experimental Investigation on the Shrinkage and Creep ...

Several experimental investigations were conducted on the autogenous shrinkage and creep performances of two types of designed self-compacting lightweight concrete (SCLC). In order to explore the difference in long-term performance between SCLC and normal aggregate concrete, normal aggregate self-compacting concrete (SCC) and normal concrete (NC) are also designed in this study.

Best Practices Guidelines for Self-Consolidating Concrete

Best Practices Guidelines for Self-Consolidating Concrete 3 WHAT IS SELF-CONSOLIDATING CONCRETE? Self-Consolidating Concrete (SCC), also referred to as self-compacting concrete, is able to flow and consolidate on its own. At the same time it is cohesive enough to fill spaces of almost any size and shape without segregation or bleeding.

Self-compacting concrete (SCC) is flowing in nature and hence viscosity modified agent (VMA) or higher amount of binder is used for stability of mix. The mix proportion of SCC is also different from normal vibrated concrete (NC). This modifies the properties of concrete at fresh as well as at hardened state. Three mixes, one VMA type SCC, one powder type SCC and one NC, are considered with ...
