Concrete with recycled aggregate
(Trans Tech Publications LTD, 2004)
Reuse of hardened concrete rubbles caused by the demolition of concrete structures has recently become possible in construction industry. The utilisation of these materials M concrete production may provide two main benefits; ...
Some factors influencing effect of core diameter on measured concrete compressive strength
(Amer Concrete Inst, 2007)
Various concrete mixtures were produced using crushed limestone and river gravels with four different maximum sizes of 10, 15, 22, and 30 mm (0.39, 0.59, 0.87, and 1.18 in.). The 28-day cube strength of concrete mixtures ...
Utilisation of Fly Ash in Geobricks Produced By Pressure Forming Process
(Novpress Sro, 2011)
In this experimental investigation, various geobricks were produced from F and C-type fly ash. A combination of sodium hydroxide (NaOH) and sodium silicate solution was used as alkaline activator. The fly ash based geobricks ...
Mechanical Properties of Cement Mortar Containing Heat-Treated Boron Derivative Waste at Elevated Temperatures
(Asce-Amer Soc Civil Engineers, 2018)
The largest boron reserves in the world are located in Turkey. The production of boron compounds and use of generated boron derivative waste during this production are extremely important for both economically and ...
Statistical distributions of in situ microcore concrete strength
(Elsevier Sci LTD, 2012)
Quality control processes require accurate knowledge of in situ compressive strength of concrete. The most widely accepted method of determining the compressive strength of concrete in existing structures is to test core ...
The effect of heat-treated boron derivative waste at 600 degrees C on the mechanical and microstructural properties of cement mortar
(Elsevier Sci LTD, 2017)
Turkey holds 73% of the world's boron deposits. 25.3% of the total deposits are tincal ore and located in Eskisehir Kirka region. During the production of 1 million tons of borax pentahydrate (Na2O center dot 2B(2)O(3)center ...
Assessing concrete strength by means of small diameter cores
(Elsevier Sci LTD, 2008)
Estimation of concrete strength may be gained from compression tests conducted on cores having a diameter considerably smaller than the recommended one of 100 mm. This paper examines the results of tests applied on the 69 ...
Effects of sulfates on strength of Portland cement mortars
(International Society Offshore& Polar Engineers, 2005)
Concrete is a composite material which is produced by mixing cement, aggregate, water and if required admixtures. The quality of mixing water plays an important role in the mechanical behavior of hardened mortar and concrete. ...
Determination of elasticity modulus of low strength concrete and its effect on the risk assessment results by DSVB
(Gazi University, Fac Engineering Architecture, 2017)
Turkey is frequently exposed to destructive earthquakes causing loss of lives and property. There are many factors that affect the seismic vulnerability of existing buildings. Poor concrete quality is a major and widespread ...
