Concrete durability largely depends on the possible corrosion of reinforcing bars in an aggressive environment, resulting in cracking and spalling of concrete. Enter the email address you signed up with and we'll email you a reset link. Hydraulic cement concretes were produced using pozzolans and ground, granulated, blast-furnace slag (slag) to investigate the effect of these materials on durability.

Ordinary Portland cement (Density: 3.15g/cm3, Blaine fineness: 3,300cm2/g) and ground granulated blast furnace slag (Density: 2.89g/cm3, Blaine fineness: 4,150cm2/g) are used as binder.As a fine aggregate, crushed sand (Density in saturated surface dry condition: 2.65g/cm3, Water Pastes were prepared with a water-cement-ratio (w/c) of 0.45 by weight with common tap water. Such enhancement other than bringing down the carbon footprint of cement conserves natural resources. ]ľ��\$�B�~��W��#V�PĐ��hU{͏��+��_��u��LlRp[ԯ�"}�C>�R��]Q�(R��rGIq����J!���I�,��X�~��׷8vM�vt�U�n��ګ��2He �8/Ճ� H%�\t���㩫�*��v+o\����� �Y{b|��p���3T���Ŋ�l��&,O!��4�q��,Ky6�%VhI�J�QTUIl~�}(g���������ѓ� �d��H8^Ñ1Y�A�t0`[��d���R����,E�Zt��8�1�o�I This specification covers three strength grades of finely ground granulated blast-furnace slag (Grades 80, 100, and 120) for use as a cementitious material in concrete and mortars. The slag shall contain no additions and shall conform to the sulfide sulfur and sulfate chemical composition requirement. 2. Slag Cement Granulated Blast Furnace Slag 8 İSKENDERUN GRINDING AND PACKAGING PLANT: İskenderun grinding and packaging plant was established by ÇİTOSAN on 17 September 1974. The activation of blast-furnace slag with alkaline liquids (e.g., NaOH or water glass) to produce alkali-activated slag cement However, beyond 70% slag incorporation, early strength gain of PSC is meagre because of its low reactivity. SLAG Ground granulated blast-furnace slag (Fig. In this study, slag cement (SC) is used to prepare different slag cement mortar (SCM) mixes to study mortar microstructure perspectives, physiochemical properties, mechanical properties and durability performance. Using the same admixtures, the properties of the blended cement with 70% additives could reach the standard of 525-grade slag cement according to GB. � �����H�A{���S�]�n�qc��c�f�l��گ������*;q��qp�[������� ��ZaG��X�����-D�{}�AG�C�T���Z��.�.0c�#s�'�l���E��_+�ƥE�'�'��b��?����_Sf�J���gW�$�l����?��s�o����u���˛���*�7�'��z�aV�ԑ̪6�%���n��E��c@���^��k�n߄�ZP��;��>�7���_�ܠ�d'C��XΑ��A��e��m��f�^���C4�`��3����(!G�0_P ]�^��*�����T�h=�̵Ð4 �'���h���i Appendix A contains a list of TAG members and Appendix B gives its terms of reference. Slag was processed by 28 companies servicing active iron and steel facilities or reprocessing old slag piles at about 129 processing plants (including some iron and steel plants with more than one slag-processing facility) in 33 States, including facilities that import and grind unground slag to sell as ground granulated blast furnace slag (GGBFS). �h�r�� blast-furnace slag and fly ash has been reported in many research works [5,6].
