“…We note that the initial setting time of the cement increases with the substitution rate of CEM I by Tuff compared to the reference paste without Tuff. Several authors in the literature find similar results [25,26]. This behavior is attributed to the dilution effect resulting from the decrease in clinker content in mixtures.…”

This paper presents the feasibility of using locally available limestone Tuff in Burkina Faso as a partial replacement for CEM I artificial Portland cement. To this end, standard tests were carried out in the laboratory on mortars containing variable proportions of Tuff in partial substitution of CEM I cement. These include heat of hydration, setting time, total shrinkage, compressive strength, capillary absorption and resistance to acid attack. The experimental results obtained show that Tuff can be used as a natural pozzolan. It is also noted that the incorporation of Tuff into cement has virtually no influence on the transfer properties of mortars. However, at a rate above 15% partial substitution of CEM I, the mechanical strength of mortars is considerably reduced. This is probably linked to the finesse of the Tuff used. A finer shredding improved the mechanical activity index. However, we note a better resistance to acid attack (sulphuric acid that can come from acid rain) of mortars containing Tuff compared to mortar based on artificial Portland cement. All these results have shown that the Tuff used in this work can be a solution for reducing CO 2 emissions in cement production and also in reducing the price of cement in Burkina Faso.

“…It is well known that the onset of significant C-S-H formation is the main cause of cement setting, the mechanism that governs the transition from plastic phase to hardened one is characterized by an increase in the system's viscosity. It is true that the cement setting time depends to the w/c ratio [23,24] and the cement fineness [25], but the SO 3 content remains more efficient. The effect of gypsum content on setting time of cements is presented in Fig.…”

h i g h l i g h t s Gypsum is a cement setting regulator, it is also a cement hydration accelerator. The use of gypsum at the optimum content, improves several cement properties. Its use below or above the optimum, affects adversely the cement properties. The optimum gypsum content is not fixed at 5%, it varies from a cement to another. The optimum gypsum content depends mainly on: SO 3 %, C 3 A %, Alkali % and cement SSB.

“…Thus, owing to the large disposal of eggshells and locust bean pods has prompted the need convert waste to wealth. The setting time is influenced by several factors such as cement composition, water cementitious material ratio, temperature and supplementary cementitious material [2]. Setting time refers to the degree of stiffness of cement mixture to resist penetration of weighted test needle.…”
