Compressive strength of heated high-strength concrete
Magazine of Concrete Research, 2007The present study is aimed to study the effect of elevated temperatures ranging from 50 to 250°C on the compressive strength of high-strength concrete (HSC) of M60 grade made with ordinary portland cement (OPC) and pozzolona Portland cement (PPC). Tests were conducted on 100 mm cube specimens. The specimens were heated to different temperatures of 50,

Composite Compressive Strength
1994The importance of composite compressive strength is fortified by the wealth of published literature pertaining to this subject. A literature search disclosed more than 350 references. Approximately twentyfour references were identified as important developments and span the timeframe since 1981. Older references, although important, are not cited since

The Strength of Masonry with Low Compressive Strength of Mortar
Advanced Materials Research, 2014The article deals with a problem of determination the strength of masonry for low grade mortar. This situation can occur with fresh mortar or in historical massive buildings. Results of different equations according to several authors and standards were compared and expressed in graphs. Authors propose the minimum value of mortar strength being used in

Testing High-Strength Concrete Compressive Strength
ACI Materials Journal, 1993Comparative testing reveals that high strength concrete (HSC) compressive strength values are greater by 5% when measured on 100 x 200 mm specimens. Moreover, the coefficient of variation on one set of three 100 x 200 mm specimens is as small as, or smaller than that for 150 x 300 mm specimens.

Slow Compressive Strength of Amalgam
Journal of Dental Research, 1972An investigation of the compressive strength of amalgam at various loading rates revealed that the strengths of several commercial amalgams loaded at 0.001 inch/ minute were correlated (r = 0.931) to their respective dynamic creep values.

Strength of the Cervical Spine in Compression and Bending
Spine, 2007Cadaveric motion segment experiment.To compare the strength in bending and compression of the human cervical spine and to investigate which structures resist bending the most.The strength of the cervical spine when subjected to physiologically reasonable complex loading is unknown, as is the role of individual structures in resisting bending.A total of

Compressive strength of spruce glulam
European Journal of Wood and Wood Products, 2012Tests on glulam were simulated to determine the compressive strength. Based on the values obtained, three strength models were derived. They describe the compressive strength in terms of the density of the sawn timber used, the moisture content of the glulam and, optionally, of the knot area ratio.

Compressive strength of technical sitals
Strength of Materials, 19761. The sitals tested in this investigation exhibit a very high compressive strength (200–270 kgf/mm2); their specific strength is 3–4 times greater than than of present-day metallic construction materials. 2. The distribution of the compressive and bending strengths of sitals obeys a normal law.

In this chapter, the probabilistic porous-solid model is used to determine the mean effective stress of soils at failure. The plots of the deviator stress against the mean effective stress show a unique failure line for a series of triaxial tests performed at different confining net stress and suctions for both wetting and drying paths. This result

The dynamic compressive strength of aluminas
Journal of Applied Physics, 1998The plate impact loading response of three aluminas with varying glass content (purity) and porosity has been investigated using the 50 mm gas-gun facility at the University of Cambridge. The elastic precursor amplitude has been shown to be sensitive to both shock propagation distance and impact stress. The precursor decay effect is greatest in the low
