Study on Shrinkage Cracking Morphology of Cement Mortar with Different Nanoclay Particles under Restraint

open access: yesBuildings, 2022
In this paper, different types and particle sizes of nanoclay (nano-metakaolin—NMK—and nano-attapulgite—NMA—clay) were selected to study the effect of nanoclay on the properties of cement-based cementitious materials.

Evaluation of long‐term behaviour of composite timber‐concrete structures according to EC

open access: yesTechnological and Economic Development of Economy, 2005
The objective of this work is the investigation of long‐term behaviour of composite timber‐concrete beams. Both ultimate and serviceability limit states have to be satisfied according to modern design codes, such as Eurocode 5.

Model for the Simulation of the Time-Dependent State in RC Elements

open access: yesApplied Sciences, 2022
The paper presents an upgrade of the previously developed model for nonlinear 3D analysis of concrete structures extended with the possibility of simulation of the long-term effects (shrinkage and creep) under long-term static load.

Evaluation of in-situ shrinkage and expansion properties of polymer composite materials for adhesive anchor systems by a novel approach based on digital image correlation [PDF]

open access: yes, 2019
The curing reaction of thermosetting resins is associated with chemical shrinkage which is overlapped with thermal expansion as a result of the exothermal enthalpy. Final material properties of the polymer are determined by this critical process.

Effects of Fly Ash Dosage on Shrinkage, Crack Resistance and Fractal Characteristics of Face Slab Concrete

open access: yesFractal and Fractional, 2022
The crack resistance of face slab concretes to various shrinkages is crucial for the structural integrity and the normal operation of concrete-faced rockfill dams (CFRDs). In this work, the effects of fly ash with four dosages (i.e., 10%, 20%, 30% and 40%

Generalized robust shrinkage estimator and its application to STAP detection problem [PDF]

open access: yes, 2014
Recently, in the context of covariance matrix estimation, in order to improve as well as to regularize the performance of the Tyler's estimator [1] also called the Fixed-Point Estimator (FPE) [2], a "shrinkage" fixed-point estimator has been introduced ...

Pseudorandomness from Shrinkage [PDF]

open access: yes2012 IEEE 53rd Annual Symposium on Foundations of Computer Science, 2012
One powerful theme in complexity theory and pseudorandomness in the past few decades has been the use of lower bounds to give pseudorandom generators (PRGs). However, the general results using this hardness vs. randomness paradigm suffer from a quantitative loss in parameters, and hence do not give nontrivial implications for models where we don’t know
