MORPHOLOGY AND MICROSTRUCTURE OF HYDRATING PORTLAND CEMENT AND ITS CONSTITUENTS. IV. CHANGES IN HYDRATION OF A C3S, C2S, C3A, C4AF AND GYSUM PASTE PASTE WITH AND WITHOUT THE ADMIXTURES TRIETHANOLAMINE AND CALCIUM LIGNOSULPHONATE

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
