Tiivistelmä
Cement production is responsible for 7% of global carbon dioxide emissions. Because of this huge percentage, the concrete industry is one of the biggest industries, making the world less livable. It is important to reduce emissions because there is not yet anything completely replaceable for cement and concrete.
This thesis aims to make a concept recipe for TT-slabs using lower CO2 emission cement in the market. In particular, the TT-slabs topic has been chosen as a research topic because the commissioning company Suomen Kovabetoni Oy has an existing recipe of less CO2 emission cement for elements such as beams and columns, by which the company has achieved good results considering the reduction of CO2 emission.
Many factories can make less emission concrete elements but to optimise the resource, time plays an important role. Another aim of the thesis is to achieve a recipe where production and material costs do not increase.
As a prefabricated element, TT-slabs are thin elements. Getting 60% of the final strength of the used concrete class is very important in terms of safety and resources and that also plays a critical role in maintaining the strict mass production timetable.
Finding out the solutions to this matter is the target of this thesis by testing different mixing ratios of CEM-3 and RAPID cement at different times.
