The compressive strength results of marble powder concrete are compared with the literature and presented in Fig. 8. Based on regression analysis of 40 experimental findings, the equations for estimating compressive strength (f ck) have been proposed as (1b) f ck = 9.5941 × (w/b) −1.857
However, compressive strength at 05% recycled aggregate and 05% stone dust is marginally than that of conventional concrete. The compressive strength of 05% stone dust and ceramic waste sample is in close proximity of the referral concrete. Thus, it can be concluded that stone dust up to 05% with 05% ceramic waste aggregate is satisfactory …
The compressive strength test of granite is ranging from 1050 to 1358 kg/cm 2, for marble the results ranging from 827 to 1020 kg/cm 2. A dry density result of granite is 2.69 and marble dry density is 2.62.
Coral islands are tiny and are scattered in deep seas throughout the world, hundreds of kilometres away from the mainland. For construction activities in these …
Fiber-reinforced concrete technology has emerged as a critical innovation in the field of civil engineering. Introducing various types of fibers into concrete effectively enhances their resistance to cracking, tensile strength, and impact resistance [10], [11], [12].These fibers can be categorized into two groups based on their size: micro fibers …
It was found that concrete containing the ground coarse fly ash (FAG) replacement between 15% and 50% can produce high-strength concrete and 25% cement replacement gave the highest compressive ...
The rock structure and three-dimensional stress state play a vital role in the mechanical behaviour of rock masses. Here, a series of true triaxial compression tests (σ1 > σ2 > σ3) are conducted on jointed marble (50 × 50 × 100 mm3) containing a natural stiff joint, taken from the China Jinping Underground Laboratory (CJPL-II) project. The …
Around three million tons of waste marble powder (WMP) are generated by the ornamental stone industry each year [1].The uncontrolled disposal of WMP can cause environmental problems in the surrounding ecosystems, including reducing the soil's porosity and permeability, and compromising its overall fertility [2].From a sustainable …
Coral concrete consisted of cement, coral, coral sand, FA, SG, sisal, water reducer, and seawater. The details of the mixture proportions are listed in Table 4.Different strength grades of coral concrete specimens with dimensions of 100 × 100 × 400 mm and 100 × 100 × 100 mm were casted and cured under sealed conditions for 24 h.
Although the porosity of coral aggregate decreases with the decrease of particle size, the interface bond between fine aggregate and cement stone decreases compared with coarse aggregate, resulting in the flexural strength and splitting tensile strength of the high-strength coral concrete to increase less significantly with …

RH is a simple, convenient and useful method to evaluate the quality of concrete based on its surface hardness. The rebound number (RN) is obtained from the rebound of the mass of concrete when the rebound hammer impacts the concrete with a defined energy, which can reflect the concrete strength with a depth of 10–15 mm. …
Slag and sodium hydroxide (NaOH) contents have remarkable effects on the compressive strength of alkali-activated slag-fly ash geopolymer concrete. The addition of slag is beneficial to enhancement of compressive strength, and the relatively optimal coarse and fine aggregate contents are 1200 kg/m 3 and 750 kg/m 3. It is noted that …
