In this study, an artificial neural networks study was carried out to predict the compressive strength of ground granulated blast furnace slag concrete. a data set of a laboratory work, in which a total of 45 concretes were produced, was utilized in the anns study.
Artificial aggregates are made out of various waste materials. artificial aggregates are sometimes produced for special purposes for making lightweight concrete burned clays, artificial cinders, foamed slag, expanded shales and slate, sintered fly ash exfoliated vermiculite are used for making heavy
While compressive strength of concrete with slag substitution at age 1, 3,7,14 and 28 days respectively are 43.896 mpa. 71.541 mpa. 77.282 mpa. 70.658 mpa and 75.958. thus it shows that high quality concrete made of steel slag as the main constituent aggregate has a compressive strength greater than that of conventional

Feb 22, 2016nbsp018332key words steel slag aggregate, artificial sand, opc, compressive strength, coarse aggregate. introduction conventionally concrete is mixture of cement, sand and aggregate. properties of aggregate affect the durability and performance of concrete, so aggregate is an essential component of concrete.
Steel slag is a byproduct of steel making processes of steel industry. its also one of the biggest industrial waste which is being produced worldwide in a huge quantity. this research deals with substantial replacement of natural aggregates and
Jun 20, 2018nbsp018332the current study adopts the results of completed laboratory experiments for modelling the strength properties of steel slag aggregate concrete using artificial neural network ann technique. note worthily, the considered experiments reported that strength properties increased with increasing curing age.
From the biochemical research, steel slag aggregate can be evaluated as the material that is ideally suited for promoting propagation and reproduction of seaweeds and sessile benthos. discover the ...
The use of blast furnace slag and steel slag as the major raw materials in the preparation of artificial reef concrete not only provides an potential solution for the comprehensive utilization of by
Contents of cement, blast furnace slag, fly ash, water, superplasticizer, coarse aggregate, fine aggregate and age in days have been taken as inputs and compressive strength as output for gpr ...
Steel and steel slag annual output of 2010 in china reached to 626.7 million tons and 90 million tons respectively 2. however, the current utilization rate of steel slag in china is only 22, far behind the developed countries like usa, japan, german and france, of which the rates have been close to 100.
Compressive strength of steel slag aggregate and artificial sand in concrete, international journal of civil engineering and technology, 62, pp. 16
Compressive strength of steel slag aggregate and artificial sand in concrete. steel slag is a by product of steel making processes of steel industry. its also one of the biggest industrial wastes which are being produced worldwide in a huge quantity. this research deals with substantial replacement of natural aggregates and natural
Electric arc furnace steel slag on hardened concrete. they concluded that using steel slag aggregate concrete leads to higher values of compressive, tensile, flexural strength and modulus of elasticity compared to natural aggregate concrete.the resort to artificial aggregates such as the
Today, iron and steel slag is used in many fields where its unique characteristics can be put to effective use. as a result of growing environmental awareness, iron and steel slag is highly regarded as a recycled material that can reduce impacts on the environment due to its resourceconservation and energy
Compared with the blast furnace slag, steel slag has the expansibility due to the reaction with water and free cao. therefore it is specified in standard specification for concrete in korea that steel slag aggregate must not be used in concrete. so it is unusual to use steel slag aggregate in concrete.
Piles of steel slag, a solid waste generated from the iron and steel industry, could be seen due to no utility found for the past century. steel slag has now gained much attention because of its new applications. the properties of slag greatly influence its use and thus had got varied applications. the chemical composition of steel slag varies as the mineral composition of raw material such as ...
