The objective of this research is to know the increase of compressive strength value of geopolymer concrete using duck egg duck ash with mixture of sodium silicate and sodium hydroxide at variation 0%, 80%, 90% and 100% at 7 days with heating specimen and control concrete room temperature. Ash duck egg shell used is burnt waste with temperatures reaching 800 ° C for ± 6 hours using ceramic burning oven. This study uses cylindrical test object with diameter 10 cm and height 20 cm with the quality of plan is fc '20 MPa. Testing of compressive strength of geopolymer concrete using Crushing Test Machine tool. In this purpose, the compressive strength of the geopolymer concrete produced by the concrete test object on variations 0%; 80%; 90%; and 100% ie 0 MPa; 6,32 MPa; 8,57 MPa; and 14,01MPa, while the concrete test object No concrete compressive strength was applied on variations of 0%; 80%; 90%; and 100% ie 7,64 MPa; 4,84MPa; 5,77MPa; and 6.19MPa. It can be seen that the maximum average compressive strength value is present in the 100% variation with the tested object being tested at 83°C first.
